The Infinium Space Pen writes far longer than the standard Fisher Space Pen which normally writes three times longer than a normal ballpoint pen. In fact the Infinium Space Pens are guaranteed to write throughout the entire life of an average user without refilling the ink cartridge. Fisher stands behind their unconditional lifetime guarantee and believe that their pens are the most reliable in the world. If you are not completely satisfied with the Inifinium Space Pen or if it runs out of ink during your lifetime return it directly to Fisher for free repair or replacement.
