I am selling the handles that were attached to the LIXIL Noct cupboard because I replaced them. They were used for about one month. There are no noticeable scratches. They were attached to a drawer with a board thickness of 15mm. Screw hole depth is about 12mm. Screw pitch is P=240mm. They have a solid feel, so I think they are made of stainless steel. You can replace them with just a screwdriver. Selling 7 pieces as a set. LIXIL Kitchen Noct Cupboard Handle, Drawer Matte Black
