Image enlarged to show detail;
The PR Cartridge is the thick one in the middle.  The U Cartridge is the thin one on the top and bottom.

The Q4 Multi-Action Space Pen uses our Universal (U) cartridge.
When the U Cartridge 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 cartridge. Please note: PR and U cartridges are NOT INTERCHANGEABLE.

The Contractor Space Pen uses our RP/CSP cartridge.

Infinium and R80 Space Pens are not refillable.
