Most pens aren’t designed for extreme situations and less-than-optimal conditions. They leak, stop writing, and generally fall apart when conditions aren’t pristine. Not only does this pen look tough enough to handle these challenges, it actually can. The Matte Black Zero Gravity Pen can write on wet paper, in extreme heat or extreme cold, over grease, and at any angle, even upside down. Each is made in the USA and ready for any task you throw its way.
