AirTag (1 Pack)

With AirTag, it's easy to keep track of your belongings. Attach one to your keys, pop another in your backpack, and they'll appear in the Find My app, the same one you already use to locate your Apple devices and track your friends and family.

AirTag is designed to last over a year with a standard battery, which you can then easily replace. And your iPhone will tell you when it's time to replace it.
