This pen features a convenient, retractable design as well as Fisher's legendary Space Pen ink. The specially-formulated, pressurized ink writes smoothly and dependably upside down, underwater, over grease, and in extreme cold and hot temperatures and has an estimated shelf life of 100 years. The capacitive stylus on the cap works on smartphones, tablets, and other touch screen devices.
The pen is refillable.
