A punch that can punch up to 15 sheets of paper at once. - Brand: CARL - Model: SD-170 - Hole size: 7mm - Maximum punching capacity: 15 sheets - Maximum punching thickness: 1.3mm - Size: W25 x L109 x H82mm I purchased this at a stationery store this year for 935 yen, but I'm selling it because I don't use it. There is a slight crease on the part of the box that closes. I hope to sell it to someone who understands that it is a used item that has been stored at home.
