Fisher Backpacker Orange

The Fisher Backpacker can hang upside down forever, but it works immediately when you need it. This pen has been a favourite among enthusiasts for years due to its practicality. Attach it to your keys, backpack, belt loop, hiking gear, fishing shoulder strap, camping gear, and more.
The Fisher Backpacker is a two-piece pen with a key ring attached to the cap. Each part contains a pressurised ink refill cartridge.
It writes upside down, at any angle, underwater, on greasy surfaces, in extreme temperatures (-30 to +120 C°), on almost any surface, lasts three times longer than an average pen and, of course, in the vacuum of space in zero gravity.
