This complete set includes ten sheets of premium foam sandpaper, a maple fingerboard, and two screwdrivers for assembling the hardware. This all-in-one set provides everything you need to build a professional-grade fingerboard or refurbish existing gear with new sandpaper. The foam sandpaper is made from premium PU foam material with a soft, textured surface that enhances fingertip control. The foam structure provides excellent shock absorption while maintaining a non-slip grip; the durable material retains its grip even after prolonged use on various obstacles, including railings, steps, and ramps. Each sheet of sandpaper comes with strong self-adhesive backing that adheres firmly to the wooden fingerboard. The adhesive holds the sandpaper securely in place during use, preventing edges from lifting or falling off, and maintaining stability even during high-intensity skill practice. When replacement is needed, the adhesive backing is pre-cut to the size for standard fingerboards, but you can also trim it further as needed to fit different board shapes or achieve perfect edge alignment. The included fingerboard is made of five layers of high-quality maple wood, making it sturdy and durable. Maple wood is a common material for professional fingerboards, as it provides enough rigidity to perform actions such as dolphin jumps and kicks, while maintaining enough flexibility to ensure comfortable finger placement.
