Snack Bag with Magnetic Fastening

I'm annoyed that I didn't look more closely at the measurements before I ordered one – that's my mistake. I think it's quite big and bulky in design for a wallet to carry around every day, but on the other hand, it has a pretty handy magnetic closure, and it's cheap.

I've been using it for years, and of course, after a while the material wears out, it gets dirty because of the treats, and you have to buy a new one. The previous version had a rectangular magnet (which I think was much more practical), but the newer version has a round magnet and it's much stronger. So much so that after just a few days of use, it tore out of its place (although it was only held by quite thin material).
