The only pen you will ever need.
The Inkless Metal Pen features a tip made from solid lead. As you write, tiny amounts of the metal are deposited onto the page. The silvery markings may resemble pencil, but they are permanent and completely smudge-proof.
Because it doesn’t require sharpening or refills, the Inkless Metal Pen is an amazing gift for artists or doodlers. Its "ink" is solid, so it will never leak, and it can be used upside down or under extreme conditions. The Inkless Metal Pen works on most any writing surface and features a stainless steel barrel.
