Fisher Space Pressurized Ballpoint Refill includes Fisher's traditional pressurized ink that performs exceptionally well over grease, underwater and extreme weather conditions without hesitation. Works in temperatures from -30º F to +250º F, underwater, in zero gravity, at any angle–even upside down. The refill is specially designed for Fisher Space Bullet pens. It also fits perfectly on ballpoint pens that feature a Parker style refill using the included adapter.
