Support for placing disposable sandpaper grit 80 or 180 for pedicure services. The format of the holder is straight, in which you have the option of applying sandpaper on each side. You will notice that when you remove the sandpaper from the box, it is half curved, so you need to fold the sandpaper so that it is straight, before removing the film. Make sure the sandpaper's application area is very clean and free of glue and grease on the plastic backing. When applying the sandpaper to the plastic backing, apply the film to the top of the sandpaper grain, so when you press the sandpaper down onto the backing, it adheres to the backing and doesn't hurt your skin.
