I had these left over from a previous purchase. They're double-sided tape magnets. The one attached to the tape cutter is 1.5 cm wide. It's quite thin, so it's probably best for attaching lightweight items. The rolled-up one is 1 cm wide. It's a common type of magnet. I've taken them out of the bag, so I'll sell them at a lower price. If anyone needs magnets, please let me know. (*・ω・)*_ _) *bows* #magnet #handmade
