2 Pack for AirTag Wallet Holder Slim Card Insert for Air Tag Wallet Thin AirTag Card Holder Case, Compatible with Apple AirTag 1st & 2nd Gen, Wallet, Purse, Badge, Business Card Holder

I'm not sure about other brands but I use an insert like this that the regular Airtag fits into and then slides into my wallet like a regular credit card. It's made it so that the Airtag doesn't fall out of the wallet I use that doesn't have a built in spot for one. https://a.co/d/cIs1Ui8
