U1F - Blue Ink Fine Point Fisher Pressurized Universal Cartridge

Price: $5.25
Item Number: #U1F


Most ALL Fisher Space Pens use our PR Cartridge.  SPR and PR Cartridge are the same cartridge, the only difference is the packaging.  The S means that the Cartridge comes in a Blister Card, the cardboard backed, clear plastic holder like most things are in when you purchase them in a retail store. The following image is enlarged to show detail.
The PR Cartridge is the fat one in the middle.  The SU Cartridge is the skinny one on the top and bottom. When it arrives it will be long like the top image shows. It is made this way to fit several different pen barrels.  If you need it to be shorter, just flex it back and forth at the break point and it will separate, leaving you the correct length refill. The PR and SU Cartridge are NOT INTERCHANGEABLE!

Please note: the SU Cartridges contain a much smaller amount of ink, they write about 1200 feet depending on your writing style, as compared to our regular PR Cartridge which should write more than 12,000 feet depending on style and surface.

This is the replacement Cartridge for #Q4 Multi-Action Space Pen
Blister Carded for Peg Board Display.
