Loose-leaf punch Gauge Punch Neo Carl Office Systems CARL GP130N This punch can be used to make holes in A4, B5, and A5 paper for loose-leaf use! I bought it several years ago and used it a bit. It's been stored at home, but I think it's in relatively good condition. This is a set of a punch and gauge that makes loose-leaf easily. It's a convenient tool that allows you to punch holes in copy paper and printouts to create loose-leaf, which can then be bound in binder files and notebooks.
