The Epic Refill Reference Guide: Rollerball, Gel and Ballpoints
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.
