SU1F - Blue Ink Fine Point Fisher Pressurized Universal Refill

Fisher Space Pen PRESSURIZED REFILLS

Most ALL Fisher Space Pens use our PR Refill.  SPR and PR Refills are the same refill, the only difference is
the packaging.  The S means that the refill 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 refill is the fat one in the middle.  The SU refill 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 refills are NOT INTERCHANGEABLE!

Please note: the SU refills contain a much smaller amount of ink, they write about

1200 feet depending on your writing style, as compared to our regular PR Refill

which should write more than 12,000 feet depending on style and surface.
