I received this in a company lottery, but unfortunately, I already have one, so I'm selling it. This is the Uni-ball ZENTO, a water-based ballpoint pen developed by Mitsubishi over a six-year period. It's a new line of ZENTO ink designed to pursue the comfort of writing. This product is the top-of-the-line "Signature" model with a 0.5mm tip, featuring a magnetic cap. - Model Name: Mitsubishi Uni-ball ZENTO Signature - Color: Metallic Black - Ink Color: Black - Ball Diameter: 0.5mm - Features: Magnetic Cap Brand new, unused.
