Hole Sizing Guide
HOLE SIZING GUIDE
Will your pens fit? Below are some examples of common pens and which hole sizes you would need. Please let me know if you have questions about specific others but when in doubt, I recommend the 5/8 inch holes.
Examples of pens that fit the 1/2 inch hole size:
LAMY Safari (not AL star), LAMY 2000 ballpoint and multipen, Retro 1951 Tornado, Karas Kustoms Render K, Karas Kustoms Bolt, standard Sharpie marker, Pilot Custom 74, Pilot Custom Heritage 92, Pilot Metropolitan, Namiki Falcon (resin), TWSBI Classic, Pelikan M205
Examples of pens that require the 5/8 inch hole size:
LAMY 2000 fountain pen and rollerball, LAMY AL star, TWSBI 540/580 and VAC, Karas Kustoms Ink, Schon DSGN Pen, Pilot Vanishing Point, Sailor Pro Gear (standard), Kaweco Sport (if you'd like the cap to fit into the holes; my recommendation)
