Inkless Pen That Will Last Almost Forever

This stainless steel pen is not your average pen. It is an inkless pen that will probably never stop writing in your lifetime.

The metal ‘nib’ is made of a metal alloy that leaves a mark on most
types of paper. If written on the typical papers used in printers and
copiers, the mark it leaves is akin to those made by a pencil. However,
the mark is not erasable.
