it's good and easy to stick the Sandpaper with holder, I recommended
Overpriced scrap. The sanding board is from below, where a flat surface is required, deformed due to poor production technology. Unfortunately, the individual pieces of adhesive sandpaper are also defermered, the deformation is caused by poor cutting technology to a given size. Due to these deformations, perhaps the paper does not form a flat surface, due to which these tools are bought (to allow the part to be ground into a flat surface) and to buy these products is therefore a waste of money. The product disappointed me a lot !!!!!
