The Backpacker is a two-piece pen with a key ring attached to the cap of the pen. Each carries a pressurised ink refill cartridge, which means that they offer all of the unique capabilities that are synonymous with Fisher products: they will write upside down - at any angle, under water, through grease, extreme temperatures (-34 to +121 degrees C), on almost any surface, three times longer than the average pen, and of course in the gravity free vacuum of space, and all of our pens are lifetime guaranteed for quality against all manufacturing defects.
