This is the popular "Hand Shredder" from MUJI. I opened it and used it about twice. It's a hand-cranked, straight-cut shredder. It's compact and stands on its own, so it doesn't take up much storage space. *Usable paper thickness and number of sheets: Up to 2 sheets of copy paper (high-quality paper 64g/square meter) Up to 1 postcard (approx. 0.2mm). Special materials may not be usable. It's convenient for daily processing of personal information. It also fits in a bag, so you can carry it and shred sensitive information when you're out and about. ◇Size Approx. W18.2 x L5 x H3 cm
