Fisher Space Pen Pressurized Refill - Medium Point - Blue Ink

The Fisher Space Pen Pressurized Refill in blue ink is a direct replacement cartridge for Fisher Space Pens. The sealed, pressurized design writes reliably in conditions where standard ballpoint refills fail; upside down, in extreme temperatures, underwater, and even in zero gravity. The medium point tip lays down a smooth, consistent blue line that's easy to read without being too bold. Compatible with most Fisher Space Pen models. Beyond Fisher's own pens, this is the same refill used in Hinderer, Benchmade, and many other brands that accept Fisher pressurized cartridges. It also includes a Parker-style adapter in the package for use in Parker-compatible pens. Not sure if medium is right for you?
