Black Titanium Nitride - Black ink Infinium Space Pen.
Infinium Space Pens write far longer than our standard Space Pens, which already write three times longer than an ordinary ball point pen. The Infinium Space Pen will write so long in fact, that the average user won't run out of ink in their lifetime and that is guaranteed. This Fisher Executive Pen offers the hefty feel that today's office warrior demands. Whether working in an office or outside, the Infinium Series provides style and comfort both in its writing and its presentation even the clip can be removed for added extra comfort. As with all Fisher Space Pens, it offers extreme quality and durability on which you can always rely.
