I like to liberate refills from the assorted plastic pens I have accumulated over the years. These are all those gel pens I’ve purchased over the years from Jet Pens. While I love the flow of the refills, the lackluster plastic barrels leave me wanting.
I started opening each plastic pen and discovering that they are almost always a standard sized refill like a Pilot G2-sized or Hi-Tec C-sized. There are also far more colors and point sizes available in the full pens than in most refill-only options. Red, blue and black are fine for many folks but I want to be able to choose orange, evergreen, turquoise or purple, if the mood strikes.
By hacking the refills out of plastic pens, I created an almost unlimited supply of potential refills for my favorite pen bodies. And by using these fine gel refills, I have catapulted certain pens into EDC pens because now they are not only beautiful and comfortable but can contain the exact right refill for me.
This habit started with Karas Kustoms and the Render K and RETRAKT pens. The lengthy list of possible refills led me to create the Refill Guide and really start experimenting with trying different refills with different pens.
I even save the springs in a plastic retractable to help stabilize a refill in a machined pen. If the refill fits but is too long, trim it down with a pair of sharp scissors. Empty refills can be trimmed to add length to a too-short refill to fit into a different pen as well. With each plastic pen costing less than a couple bucks, its not a tragedy if you make a mistake.
