Kadomaru - Sun-Star Stationery - Corner Cutter

Create beautiful rounded corners with a single push.

Easily round corners like you would laminate or punch. The cut corners will be processed into a 5mm radius circle and can be used for up to approximately 3 sheets of copy paper. You can use it to round and cute corners of business cards, photos, message cards, POPs, or as a tool to prevent injuries.

I bought this as stationery but ended up with duplicates, so I'm selling one.
It has been taken out of its case once.
