Thank you for viewing the KOKUYO 2-Hole Punch PN-3NB, which can punch through 37 sheets of thin paper. This is a KOKUYO 2-hole punch. The exterior has no major noticeable scratches, but there is some discoloration on the back cover. It has been stored in a box. Hole size: Approximately 6mm in diameter Hole spacing: Approximately 8cm It seems like it can punch through about a class's worth of copy paper.
