Please read my profile before purchasing for a smooth transaction. This is a loss prevention tag compatible with the Android smartphone app "Find Hub." It's designed to fit in a wallet, similar to an AirTag. It can be charged wirelessly, eliminating the need for battery replacement. It's credit card-sized and thin, making it easy to attach to wallets, bags, etc. It's in near-new condition, but has been opened once for functionality testing. There are no noticeable scratches or stains. Some patterns may vary, but there is no difference in basic performance. It has been stored at home, and there are no pets or smokers. I am selling it because I no longer need it. 【Material】Plastic 【Size】Credit card size (approx. 8.5cm long x 5.4cm wide x 0.2cm thick) 【Color】Black Thank you.
