The Rite in the Rain EDC Pen is a fine point pen. The permanent ink writes through water, grease, and mud without clumping or smearing. This compact, all weather pokka pen survives splashes, stains, and smudges. The all-weather cartridge is pressurized, writes in temperatures from -30F to 250F, under water (up to 35 ft), and any angle. | Rite in the Rain EDC Pen, Flat Dark Earth Pokka 2-Pack, Black 0.8mm Ink, Fine Point
