Anything can happen. You could find yourself needing to jot down field notes in the Arctic Tundra or Death Valley, underwater, in zero gravity, in a rain forest, while hanging upside down, or while covered in axle grease. You need a pen that’s going to perform no matter what.
What sets a Fisher Space Pen TAD Edition apart from other pens is the technology, starting with a non-skip, textured tungsten-carbide ball encased in a stainless steel ball socket. The sealed ink cartridge is pressured at about 45 psi and contains a visco-elastic, thixotropic, solid-gel ink.
The Trekker, with its built-in key ring, was made to go anywhere. The Trekker was designed to accompany you on your adventures, attaching to your zipper pulls, packs, inside jacket pockets, belt loops or around your neck on a lanyard string. Included is a carabiner and break-away lanyard to keep it within reach. It comes with the Triple Aught Design logo laser etched onto it.
