A unique stationery item where pulling the design pattern on the pen's grip causes a reusable vinyl-like paper to emerge. After writing, it retracts automatically at high speed with a "shuu" sound when you let go. When retracted, it looks like just a part of the pen's design, so it's structured so that you can't tell at first glance that paper is built-in. Someone who doesn't know about it wouldn't be able to spot it at first glance. Various uses, such as when you don't have paper for a sudden memo, or for using as a cheat sheet. The ink is a disposable type with no refills. Brand new, unused item. We will respond with waterproof packaging and prompt shipping. #BallpointPen Ink...Gel ink Type...Ballpoint pen Body material...Plastic Body material...Plastic
