The Nomad Rugged Keychain is a robust keychain for the AirTag. The case, in which the AirTag is stored, consists of a polycarbonate frame and a TPU coating, which optimally protects the AirTag. Two covers for the case are included: one with and one without a speaker opening. When using the cover without speaker opening, the case is IP67 certified, which means it is both dustproof and waterproof, with a maximum water depth of one meter. The case with speaker opening is not waterproof. By means of the key ring, the AirTag can be easily attached to the key ring, bags, luggage or even the pet's collar. To attach the AirTag in the case, open it by a quarter turn, put the AirTag inside and then close it securely by twisting it closed. -Rugged case for the AirTags with key ring -Made of a polycarbonate frame and a TPU cover -Two different covers: One with speaker hole and one without speaker hole -Case without speaker hole is IP67 certified: dustproof and waterproof to a maximum depth of one meter -AirTags can be conveniently attached to luggage, keychain or pet's collar with the key ring -Dimensions: 5.12 x 4.3 x 1.02 centimeters.
