Fisher Pressurized Mini Ballpoint Universal U Refill
- Length: 96.8mm (3.81″) – can be cut down to 3.5″ or D1 (2.625″) size
- Manufacturer’s website: Fisher Space Pens
The Fisher Pressurized Mini Ballpoint Universal U Refill will fit any pen designed to take a plastic or metal stick refill in one of three lengths. This refill is pressurized for writing upside-down or in zero-G conditions. Its overall length is 96.8mm, but it can be cut down to 3.5″ or the standard D1 (multifunction) size of 2.625″. This refill is available in black, blue, and red ink. There are no third party refill makers that offer a substitute for this refill, although any non-pressurized D1 refill can be used in place of the shortest length of this refill.
