CARL Carl Office Supplies A4 Loose Leaf Hole Punch, 30 Holes Grip Punch (30 holes) This punch can make holes in paper of various sizes, such as A4, B5, and A5. I have been using this as a substitute, but since it's not specifically for B5, semi-circular holes remain at the top and bottom. (A5 can be punched cleanly with this.) If you are mainly considering B5, you may find that a B5-specific punch will give you a cleaner result. This is a used item, so I've listed it as having some scratches and dirt, but I think the condition is good. Please check the photos. There is no box, so I will pack it myself. (I will also use recycled materials for packaging.) Please consider this before purchasing.
