Please read the profile before purchasing for a smooth transaction. This is a loss prevention tag compatible with the "Find Hub" (formerly Google Find My Device) network, a standard feature on Android devices. Similar to Apple's AirTag, it utilizes the network of Android devices worldwide to locate lost items and determine their current position. There's no need to install a separate app; you can easily pair it from your Android settings and start using it right away. Attach it to items you don't want to lose, such as wallets, keys, and bags. In case of loss, you can check the location on a map from your smartphone or make it emit a sound to help you find it. Also, I have several of these, so please feel free to inquire if you need a specific quantity. 【Product Condition】 The main body shows no noticeable scratches or stains and is in clean condition (please check the photos). It has a compact square design with a hole in the upper left corner for attaching a strap. 【Recommended Points】 This is perfect for those who use Android and want a convenient tag like AirTag. There are no monthly fees, and anyone with a Google account can use it for free. Please use it to keep track of your important belongings, such as keys and card cases.
