Review on Mutural Portable Case: Slim Anti-Lost Black-2PCS for New AirTags Tracker – Wallet, Purse, Backpack, Card Case Compatible – Credit Card Size by Mohmed Burt

Easily fits in a wallet. It's little more than a credit card, evident when you put the security tag inside the case. I got it a few days ago and didn't actually put it in my wallet as I usually just use the tag in my suitcase when I travel. The other day I forgot my wallet in the supermarket for the first time. I didn't even realize he was missing until I got a call from the store. Luckily I got it back with contents intact, including all or most of the cash (know that good karma from the days of finding and returning wallets would someday pay off) but the security tag is now in the holder and my wallet stays in it.
