Fisher Space Pen Ink Refill (Pressurized Refill)
The patented Fisher Space Pen refill is our recommended refill if you have a pen that can use "Parker Style" refills (such as our ION Bolt Action Pen). Nitrogen-pressurized and sealed, with a tungsten carbide ball and stainless steel point, the Fisher cartridge can write in zero gravity, underwater, upside down, over wet and greasy paper, at any angle, and from -30 °F to 250 °F!
NASA, armed forces, public safety, and outdoor enthusiasts depend on Fisher’s durability, versatility, and thixotropic ink, which writes three times longer than an ordinary ballpoint.
PR refills come in a variety of point sizes and colors. Choose the one that best fits your lifestyle from the options below:
*Note: All fine point refills will come in nickel-silver instead of brass cartridges. Also please note that the product number PR4 and SPR4 are used for the same refill (Black Medium) the only difference is just in the retail packaging and blister card it comes in.
