Pen add-on - Fisher Space Pen "Cap-O-Matic," black and brass


We recommend and sell these pens from outside manufacturers that will fit our Park Sloper wallets and other notebook covers.


This fits the Park Sloper Senior and the Park Sloper Medium wallet/notebook.

It accepts the durable, pressurized Space Pen refills that write upside down and under water, and other Parker-sized refills. This is an excellent full-sized pen that won't break the bank.

The whole cap functions as the nock on this pen, it is a clicky style, not a twist.

When used in the Park Sloper Medium it sticks out the top a little bit. The brass version of this pen may arrive with a little patina already on it.

The brass will patina quickly to a dull finish.

Keegan makes nice things and this pen is an offering that fits in with his leather goods!

Great little pen- lightweight and love the brass. The "click" to engage the pen is not quite as satisfying as I had imagined, but that is a small gripe. Big thank you to the owner for super fast shipping, especially in a pandemic! Will be my first consideration when I pull the trigger on some high quality leather goods.

Awesome brass pen. Started to patina almost immediately. Looks about 60 years old now. Love it.
