Durable Material Made of high quality metal with excellent water resistance, impact resistance and shock absorption, with independent design.

NO SIGNAL IMPACT When you lose something, your AirTag emits a secure bluetooth signal to let you find it, and our protective case doesn't interfere with signal transmission, allowing you to pinpoint your location. Your command can cause the AirTag's built-in speaker to play a sound to indicate location, and our products don't dampen the sound transmission so you can hear the sound after time. EASY TO USE The case has a key ring that can be easily attached to keys, pet collars, wallets, bikes, bags, luggage and anti-lost devices, it can easily hang on your bag, purse or belt loop and you can take it anywhere. It is convenient for you to track your items and prevent them from being lost.
