All-Weather Space Pen Refill - Black

Rite in the Rain All-Weather Pen ink refill cartridges will write for a considerable amount of time. When your ink finally runs out, this refill will get your trusty All-Weather Pen back into the field. Don’t worry about the refill fitting your pen; all Rite in the Rain All-Weather Pens use the same pen refill style. This pen refill is 3 1/2″ long with black ink. WRITES THROUGH: The permanent ink writes through water, grease, and mud without clumping or smearing. PRESSURIZED CARTRIDGE: All-Weather cartridge is pressurized, and writes in temperatures from -30F to 250F, underwater (up to 35 ft), and at any angle. PROPRIETARY INK: The ink and delivery system used exclusively in Rite in the Rain Refills will write without skipping in extremely wet conditions far better than other comparable all-weather pens. INK DELIVERY: Tiny pockets in the pen’s tip will deliver the ink in the worst conditions without allowing water or air back into the Cartridge.
