Utilizing the technology behind Fisher Space Pen's revolutionary ink invented by Paul Fisher in 1948, the trekker Space Pen can hang upside down forever yet function immediately when needed.
Put it on your keychain and always have a quality writing instrument at hand. If you are a First Responder (police, fire, ambulance, medic and more), clip it to your belt and it will sail through the daily abuse it will get. If you're in an office job, clip it to your lanyard. It's the choice of mountain climbers, sojourners, farmers, and security guards.
The point of the pen is protected in the posi-lock cap and features Fisher's rubber comfort grip on the barrel for writing stability and ease. The trekker Space Pen comes with a carabiner and a break-away lanyard making it easily attachable to a belt loop, back pack, purse, climbing gear, briefcase or anything else that is within your reach.
