This is a handmade grip. It's made by reusing skateboard decks. The skateboard decks are cut into small pieces, glued together, and then processed. The original colors of the skateboards are brought out. The decks are very hard, making them difficult to work with. Honestly, it's not worth the effort. But I think it's amazing that it's reused and turned into something new. I'd like someone who's serious about having fun to use it. The arbor is also made in-house with a 3D printer, and it's designed to fit a 9.3mm ferrule. The color of the parts is black, which goes well with the colorful wood. Please note that this is a handmade product, so there may be small scratches that occur during the manufacturing process.
