I have kept this item stored away since I purchased it, and it is unused. From the MUJI website: This is a hand-cranked straight-cut handy shredder. It stands compactly on its own and doesn't take up much storage space. *The thickness and number of sheets of paper that can be used are about two sheets of copy paper (high-quality paper 64g/square meter) and one postcard (approx. 0.2mm). Materials with special properties may not be usable. Size: W 18.2cm x L 5cm x H 3cm #MUJI #Shredder
