The Epic Refill Reference Guide: Rollerball, Gel and Ballpoints

Lots of pens available these days accept either a “Parker-Style” G2 refills, a Pilot G2 refill (adds to the confusion for sure) and the Pilot Hi-Tec C style refills.  I thought I’d try to come up with a list of refills that fit into these categories. This is by no means a definitive list but should provide you with lots of options for your favorite non-fountain pens.

parker style refills

There are so many potential options for a “Parker-style” refill (which annoyingly enough is also referred to as a G2 though it is not necessarily compatible with a PILOT G2 style pen). The G2 refill is 98mm long and approx 5.8mm diameter on the main barrel.

Here’s a list of most (but probably not all) of the Parker-style refills:

  • Diplomat EasyFLOW Ballpoint Pen Refill

  • Visconti Gel Refill (Broad, Medium, Fine)

Retro 1951 + Pentel EnerGel Refill Hacking

Mike Rohde of Sketchnoting fame hacked a Pentel Energel refill (normally a Pilot G-2 sized refill) to fit into his Retro 51 by trimming the end of the refill to be the right size. If you’re willing to experiment, other refills might also survive this sort of hack. I’ve hacked the end off a few refills in my time to make them fit as well. Just grab a craft or utility knife or a sturdy pair of scissors, line up the old refill and the new refill and snip. Voila.

If you love a particular sort of pen refill, you can also lengthen a refill that’s too short by adding a bit of plastic tubing to the end of the barrel. The fine folks at Karas Kustoms provide a length of plastic tubing with their Render K, RETRAKT and BOLT pens that could be used with other brands as well or you could snip off a section of an empty plastic refill to length a new refill to fit.

The best source I found for ALL the Parker-style refills was Cult Pens in the UK. They stock over 30 different styles of Parker-style refills.  Another option is Refill Finder.


European International Rollerball / Pilot G-2 style refills

The Pilot G2 style refill, also described as the Schmidt/Euro Rollerball refill size are about 110mm long:

  • Caran d’Ache Fibre Tip Refill
  • Caran d’Ache Rollerball Refill
  • Faber-Castell Rollerball Pen Refill
  • Faber-Castell Fineliner Pen Refill
  • FORAY (Office Depot) Pen Refill For Schmidt Rollerball
  • Kaweco “soul” refill G2
  • Kaweco G2 Gel Roller Pen Refill
  • Hi-Tec-C Cavalier refill
  • Monteverde Fineliner Refill G52
  • Monteverde Ceramic Rollerball Refill W22
  • Monteverde Spring-Loaded Tip Fineliner Refill G62
  • OHTO Ceramic Rollerball Pen Refill
  • OHTO F-300 Fude Refill Black
  • Pentel LR7 Energel
  • Pilot Frixion Erasable Gel
  • Pilot Juice (removed from plastic retractable pen)
  • Pilot G2
  • Pilot LP2RF Gel Refill (Juice refill code)
  • Schmidt Capless Rollerball 8126 and 8127 (shorter models can work with an extension hack)
  • Schmidt FineLiner refill
  • Schmidt Safety Rollingball Ceramic refill
  • Schmidt Safety Rolling Tube refill
  • Schmidt RollingSupersteel refill
  • Schmidt RollingBall refill
  • Schneider Topball 850 Pen Refill
  • Schneider Topliner 970 Pen Refill
  • Sheaffer Fineliner Refill
  • Visconti Rollerball Pen Refill AA40 0.7
  • Zebra JT refill
  • Zebra Sarasa Clip refill (removed from plastic retractable pen)

Using a spring around the tip of the refill will help to stabilize these. Use either the spring provided by your pen manufacturer or steal one from a retractable plastic pen body to get the perfect fit.

Cult Pens has a great selection of these refills in their “Euro Refills” section.

HI Tec C style refills

The Pilot Hi-Tec C style refills list doesn’t look as extensive as the other refill styles but the Hi-Tec C line has a huge assortment of color options and tip widths to provide quite a variety. The Pilot Hi-Tec C refills can be purchased individually or liberated from any Pilot Hi-Tec C pen including the Maica line.

  • Pilot Hi-Tec C (available in 0.25, 0.3, 0.4, 0.5)
  • Pilot G-Tec C (same as the Hi-Tec C but renamed for the American/European market)
  • Uni-ball Signo UM-100 Gel
  • Uni-ball Signo DX UM-151 Gel
  • Uni-ball Signo Broad UM-153 Gel

I’ve found that the Uni-Ball Signo refills may need to be trimmed slightly to fit but they work great. Just use scissors, a craft knife or blade to shorten the length to match the original length. I liberate Signo refills from plastic pens found around my office as well as occasionally purchasing proper refills.

D1 style refills

Then there’s the D1 sized refills. These are the super slender and used in multi-pens and mini pens. The Sharbo-X is a great example as is the Retro 51 Tornado Touch.

The D-1 mini refills are about 66-67mm long and there are quite a few refill styles to fit into these pens:

  • Acme Black 4FP Four-Function Pen Ballpoint Pen Refill
  • Acme Highlighter 4FP Four-Function Pen Multi Functional Pen Refill
  • Aurora Mini Medium Point Ballpoint Pen Refill
  • Caran D’ache Ecridor XS Mini Refill
  • Cross Matrix Ballpoint Pen Refill
  • Cross Micro Ballpoint Pen Refill
  • Kaweco D1 Soul Ballpoint Refill
  • Monteverde Soft Roll Ballpoint Pen Refill – D1 (628)
  • Ohto R-4C7NP Needle-Point Ballpoint Pen Refill
  • Parker Mini Ballpoint Refills
  • Parker Vector 3-in-1 Ballpoint Refills
  • Pelikan 38 Ballpoint Refills
  • Pilot BRF-8M Ballpoint Pen Refill
  • Platinum BSP-60 Series
  • Platinum BSP-100
  • Retro 1951 D-1 Ballpoint Refill
  • Rotring Tikky 3-in-1 2-Color Ballpoint Refills
  • Tombow VS Ballpoint Pen Refill – D1
  • Uni SXR-200 Jetstream Ballpoint Multi Pen Refill (0.5 and 0.7mm)
  • Zebra 4C-0.7 Ballpoint Pen Refill
  • Zebra Sharbo X Ballpoint Multi Pen Refill Component – D1
  • Zebra Sharbo X Gel Ink Multi Pen Refill Component – D1

Big thank you to Dan at Karas Kustoms for giving me his list as a starting point. Thanks to The Pen Place in Kansas City for letting me try out lots of refills. The rest of my info came from Jet Pens, Cult Pens and Refill Finder.

Monteverde is modifying some of their refills to fit pens with more proprietary sizes like Lamy. Lamy is the most finicky of all the pens. If you have good alternatives for refills for Lamy rollerball and ballpoint pens, let me know.

Don’t forget to check your local office supply or pen store (even those big box shops) and play around with the pens and refills you have. You’d be surprised what might work.

I’m working on a handy printable pocket guide of all these pen refill options but I want to make sure I haven’t left anything out or gotten anything wrong. So let me know which of these refills work for you and which don’t.

Note: I have not tried EVERY refill with every pen so your results might vary. Please leave notes in the comments about your favorite pen and refill combination for other readers. Thanks!

    You are so my favourite. I’ve been struggling to find a pen to go with the magenta Pilot style refills I bought on impulse, but gave up when I kept buying pens the wrong size for them. Now I know which size it is, it’ll be a lot easier to narrow down my hunt. I hope. Thanks!

    Pilot G2s and RT V5s fit Lamy Safari and Tipos, as well as the Monteverde Artista, Acme Studio, and Libelle Sienna rollerballs. Fisher Space pen refills fit Zebra F-701. My favorite hack is a Uniball Signo .38mm refill in a Retro 51 Tornado.

      It looks to be consistent with the Pilot G-2/European rollerball size. So it should fit in anything that takes a standard rollerball refill or Pilot G-2 style.

    Thanks for the informative post! Since reading this I’ve modified a purple Pentel LR7 refill for my Retro51 – I had to tape the Schmidt end piece to it so it would retract correctly. I also bought 2 Schmidt Fineliner refills (hadn’t been able to find fineliners since Monteverde stopped making them) and put them in a Faber-Castell pen and a Parker Frontier. The latter is now a budget-priced Parker 5th technology of sorts. It also required some scotch tape padding around the barrel and end, as the normal Parker rollerball refill is quite a different shape.

        the ohto probably does but it is over $10 for one on amazon, plus shipping!

        pilot, would have to try it, but the final tip has to be very very thin
        ”needlepoint” they call it

          It looks like Jet Pens might stock what you need. Try this one, and if you order $25 or more, shipping is free.

    I was doing some experimenting with the P8126 for a friend trying to find compatible pens and discovered it fits Lamy rollerball pens, like the Al Star

    For Lamy rollerballs, the Schmidt P8126 (Tornado refill) will fit with a spacer as a replacement for the M62/63 and seems to work fine for the M66 for the Lamy retractable pens. The longer Schmidt 8126 is the same length as the M66 so it might work as a drop-in replacement, but the longer 8126 is still shorter than the M62/63 so a spacer would still be needed.

    The Schmidt 8126/P8126 is a way better refill than the M62/63 and M66.

      Just wanted to post a quick update about the Schmidt P8126 and Lamy rollerballs. The Schmidt P8126 will NOT for the Lamy 2000 rollerball. The P8126 is too fat. Any Pilot G2 sized refill will also fit Lamy Rollerballs, again using a spacer to fill in the backspace.

    Have I missed something, or do the words “Parker Rollerball” never appear in the article? From it appears that Sheaffer rollerball refills are the same size, but little else, without using a spacer.

    • Ana
      October 9, 2014 at 4:11 pm (6 months ago)

      You are correct. I don’t think I listed Parker Rollerballs in the refill guide. I’ll try to remedy that at some point. The Parker Rollerball refill seems to be a very specific size according to their web site. Very unfortunate.

        December 1, 2014 at 12:52 pm (4 months ago)

        A medium refill came with the Parker Rollerball. The line produced while writing was way too wide for me, so I purchased an official refill, which Parker called “Fine.” Even that line was too thick for my liking, so I bought Pilot VBall XFine refills (I had been using VBall throw-aways), anticipating that I would need a spacer & a bit of tape toward the bottom of the refill to assure a tighter fit. It’s worked even better than I had thought! Without any spacer at all, with simply an inch or so of tape (I used clear) wrapped near the bottom of the refill, things are snug, rattle-free, and the extra fine line allows for even small printing. Excellent!

        • jadekraut
          December 18, 2014 at 8:51 am (3 months ago)

          Update: after 2 weeks of use, the tape I put toward the bottom still kept things snug, but the cartridge moved and so a spacer was needed. I used part of the cap that came with the Parker refill, i.e., I trimmed about 2-3mm off the open end of the cap. It fit very well onto the end of the VBall refill and I will just need to transfer that spacer to any other VBall refill that I use.

    Mont Blanc refills are about 122mm long. is there a standardized name for them like for the D1 refills? i’d like to try some other rollerball refills in my starwalker and meisterstuck series. Please help

    • jmreekes
      October 31, 2014 at 7:53 am (5 months ago)

      I think they’re referred to as Mont Blanc style refills. Monteverde refills are nice.

      • jmreekes
        October 31, 2014 at 8:11 am (5 months ago)

        I know Mont Blanc refills have some threads near the tip of the refill to screw the refill into the pen. Pilot G2, Pilot Juice, Schmidt 888 and the other rollerball & Pilot G2 refills listed in the article are shorter than Mont Blanc refills but are the same size in every other way but they do not have the threads. Normally I would say cut a spacer to fill in the backspace and you would be good to go, but I don’t know how well the non-Mont Blanc style refills would work with out the threading.

        An easy and cheap way to experiment would be to pick a pack of Pilot G2 refills (because they are readily available almost everywhere and are cheap) and see if they would be useable in your pens without the refills having the threading. As far as making a spacer, small plastic tubing is ideal, IMO, (like the back part of cheap ballpoint pen refill) though anything that could be cut down to fit should work.

    • Ana
      November 3, 2014 at 11:51 am (5 months ago)

      The Uni Power Tank refills might be a good substitute. The Power Tank pens are pressurized for extreme writing conditions and look to be a standard European/Pilot G-2 size. At $1.65 per refill, its probably a safe gamble to try one and see if it works. Please drop me a line if it works and I’ll add it to the refill list.

    I’m a convert to really bold point gel pens I have a few nice Waterman ballpoint pens and would like to convert them to gel bold pens. I think that Monteverde is making a fine point gel refill that will work in a Waterman ballpoint pen. Anyone know of a bold point refill or a hack of another type so I can rescue my nice Waterman ballpoints?

    Thanks Everyone

    FYI–I have a Zebra Tele-scopic pen and want several black refills for as low a price as I can get. I think the pen comes with a 1.00 (medium) point. Refills are 2 5/8″ long and come in black, red or blue ink, and .07 (fine) point or medium point. These slim refills fit multi color pens, too. Many places sell the Zebra brand 4C 2-pack of fine point–Amazon, eBay, They fit Zebra’s Tele-scopic, Styluspen, and Twist. I searched “mini pen refill” on eBay and found those, plus listings for 5- or 10-piece lots of generic medium point refills, and for Zebra fine point refills.

    Schmidt makes a fine point refill: the barrel says 628 F. The model numbers are 62811 (black ink), 62812 (blue ink), 62813 (red.) I could not find this model on any site but eBay. That listing says it fits: Aldo Domani®, Aurora®, Bexley®, Bossert & Erhard®, Colibri®, Delta®, Diplomat®, Elysee®, Faber-Castell®, Inoxcrom®, Jean Pierre Lepine®, Krone®, Marlen®, Montegrappa®, Monteverde®, Nettuno®, Omas®, Pelikan®, Retro 51®, Rotring®, Sensa®, Stipula®, Visconti®, Yafa®”

    Some websites say the Schmidt 635M (on the barrel of the refill) replaces 62811, but the M means medium point. People on Amazon were frustrated at ordering the pen and getting medium point (wanting fine) or ordering the refills and getting fine point (wanting medium.)

    Anyway, it was a long surf to find this out. Hope you add it to your guide and that it helps others.
