Pen Cartridge - 0.3mm

Pen Cartridge - 0.3mm



This is the replacement cartridge for the Pen Type-A and Pen Type-B. It uses gel ink, so it doesn't smear when your sweaty hands rub over what you've just written. There are several other colors and line widths out there, but the one we carry is 0.3mm wide (pretty thin) and black.
