These are great for holding bundles of anything together such as magazines file folders cook books etc. I use them for keeping containers closed in the kitchen nor refrigerator. Keeps boxes shut without tape for frequent access for example for easily adding or finding sewing notions greeting cards etc. in the closet.
These worked well for the intended use which was to organize files and paperwork. They were strong and did not break... wish I'd had these growing up and in rubber band fights" with my brother!
