Diamond Knurl Rollerball Pen Kits
Turn a pen that draws the hand in before the eye even registers what's different — the Diamond Knurl Rollerball Pen Kit wraps a Jr-size rollerball platform in precision diamond-knurl textured hardware and a decorative knurled center band that gives every finished piece a machined, custom look. The postable cap keeps the pen balanced in hand, while the Schmidt 888 fine rollerball refill delivers a smooth, consistent line from the first stroke.
Built on the compact Jr Gentleman II platform, this kit uses two tubes for a clean, two-piece barrel — easy to turn, easy to assemble, and a great choice for both newer turners and experienced pen makers looking to add a distinctive rollerball to their lineup.

Diamond knurl texture on the barrel hardware adds premium machined depth and a confident tactile grip
