My favorite pen is the superb Cross Selectip rollerball. Sadly, all but two of the Cross pens that take this refill (and I’ve got a BUNCH) require you to uncap it to use it. Only the diminutive Cross Click, which is too small for my hand, and the Cross Edge, which I find impossible to open with one hand, operates without a cap. I’m looking for a pocket pen I can operate with one hand – either push-button or twist – that takes the Cross Selectip rollerball refill. Does anyone else make one? Thanks, Gary

The new Ti Arto Kickstater project from Big Idea Design claims to accommodate 200+ refills would be perfect but it, too, is a capped pen. So, I turn to the Karas Kustoms RETRAKT and a little refill hacking to solve your problem. The RETRAKT is available in aluminum and brass and is a wider barrel pen body, comparable in width to a Sharpie permanent marker so should feel quite substantial in the hand. I use and aluminum barrel version which is weighty but can be opened and closed with one hand. My husband has a heavier model with a brass grip section if you want something even more substantial. Prices for the RETRAKT start at $55.


When you purchase a Cross Selectip rollerball refill, it comes with a little plastic cap. Keep this! It is the key to my little hack. Though I suspect a rubber band or string could be used as an alternative. I cut the wide part off and used about 1/8″ or 3mm of the plastic sheath as a spacer between the base of the refill and spring to provide a bit more length to the refill barrel for the spring to travel along. I also needed to shave a little bit of the nubs off the blue cap in order to fit into the barrel of the RETRAKT. You might find a little more plastic is better (or a little less) but there is more than enough left from the cap to experiment a bit.


This last photo shows the Cross Selectip rollerball refill fully extended, with my little plastic mod and the spring inside. Voila! As Tom at Goldspot Pens likes to tease, I’ll hack any pen and any refill.

  1. Ana – you’re a genius! Great job on the hack Cross Pen / Karas Retrakt hack! I own quite a few Karas Kustoms pens and was wondering if you could offer any suggestions on a fiber tip refill for the Karas Render G2?

    • There is a fiber tip option available from Schmidt as well for the Render but I think its only available in a single width. I suspect this hack, or similar will work with the Render K line and the Cross Selectip Fiber. I’m willing to give it a try since I have both of them in house as well. I’ll keep you posted!
