Its a paper or cardstock punch out.It punches the shape for you from the paper for crafting. This is a corner punch out so it punches out corner pieces in the shape as shown.
Thanks for your reply. Sometimes sellers never answer the questions so I appreciate you but have to say that this is unfortunately not something I would use.
You are very welcome and glad I could help with it. Its ok you can not use it. I do appreciate you asking though. I always try to respond to people cause if a question it is better to know then not. :)
