I use this with my bottle caps to cut out inserts and this is just the right size to fit inside the bottle caps I also purchased from Amazon.

I purchased the 3 incremental sizes and they work flawlessly together for cardmaking, photo cropping and matting!

Not many hole punches are sized correctly

It works great, and is the perfect size for my bottle cap images

It looks like the metal part that punches through wasn't the right size and hits the opening

unfortunately they are the wrong size

Perfect size for pictures used in bottle caps

They work perfectly and are the right size
