Review on [4 Pack] Soft TPU Case Compatible with Apple AirTags 2021 - Protective Anti-Scratch Lightweight Waterproof Cover with Key Ring for AirTags Finder Tracker Keychain - Buy Now! by Brian Kingsford

UPDATE 09/18/21: I've been wearing these for a few months now and am very happy with them. They close very securely even without a key ring. Oh, and I figured out where to put the fourth one - on a walking artist cat! I bought 4 packs of different colors. I like that they are transparent as my airtags have been engraved and you can see the engraving through the case. They arrived quickly and well packaged. I have one attached to my keys with the key ring that came with it, one in my purse and one in my car. I haven't figured out what/where to use the latter yet. These covers are simply pushed open and closed again to insert the Airtag. Added security when using the included key ring is that the ring holds the two sides of the case together.
