This is a compact paper cutter. The maximum paper thickness that can be cut at once is approximately 5.5mm, which is equivalent to about 60 sheets of 64g/m² copy paper. It can be folded, so storage is not an issue. https://bungu.plus.co.jp/product/cut/papercutter/pk-213/ A set of replacement blades is also included. I purchased this used several years ago and used it to cut books, pamphlets, etc. I used it about once a month. As this is a used item, please refrain from purchasing if you are concerned about minor details.
