This is a "glisser" that easily turns copy paper into loose-leaf sheets. It can punch holes in up to 5 sheets at a time. Thicker paper is difficult to punch, so paper around the thickness of copy paper works best. There is no box, so there are no instructions, but there are warnings on the back. The slider (blue part) has several small scratches, but I don't think it will affect its use. The width is 46 centimeters. It weighs over 1 kg, so it's quite heavy. I've used it quite a bit, but it's still a durable product that will continue to be useful.
