Polykarbonat Vertex reservoarpennagrepp

The hand-sanded polish makes a real difference — the surface feels silky smooth and doesn’t pick up fingerprints like I expected. I grabbed the blue option and it threads onto my pen perfectly, no wobble at all.

The transparent finish on these grips shows off the pen's inner workings beautifully, and the hand-polished surface feels silky against my fingers. Swapping in the amber color took seconds and totally changed the pen's look. So glad I snagged a backup set.

I grabbed the frosted blue option and the hand-polished surface is so smooth it’s almost slippery, but that’s actually great for long writing sessions. The machining is precise—threads onto the pen body perfectly with zero wobble—and I’m honestly surprised how much better the pen feels balanced now.
