Write literally forever in metal with the Wellesley Inkless Pen. It features a metal alloy tip that lays down grey markings resembling pencil marks but are permanent and smudge-proof. It does not require sharpening or refilling. As there is no "ink," it will never dry up or leak. The metallic blue barrel is made from an anodized aluminum. Please refer to the writing sample on the 3rd photo for weight and color of the lines this pen produces.
