S.T. Dupont

S.T. Dupont is a French maker of fine goods including pens. Their fountain pens take a standard international ink cartridge or piston converter. Their ballpoint pens take their own branded Parker style G2 or D1 standard refills. Some ballpoint pens take a Cross style C1 refill that is a couple mm shorter than a standard C1. Their rollerball pens take a non-standard capped rollerball or mini capless rollerball (similar to Schmidt mini 8126) refill.
