Review on Get a Fluorescent Set of 4 Soft TPU Cases for Apple AirTags - Protective, Lightweight, and Waterproof with Key Ring for Convenient Tracking and Security by Marc Stewart

9/18/21 UPDATE: I've had them 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.
