This is a set of Keroppi's tri-color ballpoint pen & mechanical pencil and eraser. The ballpoint pen & mechanical pencil are from about 10 years ago and have been stored after being used for a test write. In my amateur opinion, there is no noticeable damage and I think it's clean, but the grip part seems slightly dull, so please refrain from purchasing if you are concerned or seeking perfection. In addition, I confirmed that it can be used by test writing during the shooting. The eraser is from about 28 years ago and is unopened. *Please refrain from purchasing if you are nervous about home storage. *Please contact us via comment before purchasing if you have any questions. *Please refrain from price negotiations. Type of writing instrument: Ballpoint pen, mechanical pencil Number of ink colors: 3 colors
