You'll always have a pen on hand with this stainless steel keychain pen. Even better, it will always be returned to you since it attaches to your key ring, Every Day Carry or purse. With its pressurized ink cartridge, the pen will write in any position and at any angle - making it the ideal writing instrument to bring on an airplane when you need to fill out declaration forms or a crossword to pass the time. 

Instead of relying on gravity to pull the ink, the pen's pressurized cartridge is charged with a small amount of nitrogen that provides a consistent flow which can only be activated with the pressure of writing (so no need to wear a pocket protector or worry about ink blotches). Jot down a quick note against any available surface without worrying about a start-and-stop ink flow.

Use & Care

No special care is required for this stainless steel keychain pen.

Production & Design

This compact keychain pen was produced by a gentleman in Iowa. He carries one on his own keychain everyday. He designed the pen with a pressurized ink cartridge so that you can write efficiently in any situation or position you may unexpectedly find yourself in.

Paul C. Fisher invented the pressurized ink cartridge in 1965 with astronauts and their zero-gravity journeys specifically in mind. In October 1968, Mr. Fisher’s pen was standard issue for the crew aboard Apollo 7.
