Made using skateboard decks. The skateboards were cut into 3x3cm pieces, stacked about 13 layers high, pressed together, and then sanded. The original colors of the skateboards are used to create a colorful finish. If you're serious about having fun fishing, please give it a try. Skateboard enthusiasts and those who love street culture are also welcome. The inner diameter is 13mm and the depth is 92mm. It is attached to a Brightliver Ice Pod for easy visualization. The product is the grip only.
