Take advantage of Fisher's patented Space Pen pressurized refill technology.
Now, you can use the same refills that the actual NASA astronauts use. The pressurized refill keeps the ink flowing, allowing you to keep writing upside
down, over wet surfaces, and even in zero gravity. The large Millenium ballpen is guaranteed not to run out of ink for the lifetime of the owner, or Fisher
will replace it free of charge.
