High endurance and high versatility! GodHand No. 240 Kamiyasu Sanding Stick is a series of durable sanding sponges with a cloth-based rasp. Unlike traditional sandpaper, the abrasive side of the sponge is made of cloth, making them hard to tear or add wrinkles and folding marks... Even after wrinkling & folding! The high durability means you can even pinch your Kami-Yasu with a tool such as pliers and work away with ease. When eventually clogged, you can recover most of the usability by removing debris from the sponge using a separately purchased toothbrush or inexpensive melamine sponge, so you won't need to replace your Kami-Yasu often. You can also rinse the sponge or immerse it in water, and they can be used either wet or dry.
