The AirTag Rugged Keychain from Nomad is a waterproof enclosure that can be engraved and used for pets. Rugged Keychain is available in both black and white colorways and comes with two enclosure options. You'll have the choice between an IP67 water resistance rating or a speaker-hole version. AirTag by itself has an IP67 resistance rating allowing it to stay submerged in a meter of water for up to 30 minutes, but by putting AirTag inside the water resistant Rugged Keychain enclosure, that protection is bolstered. Use the enclosure with a waterproof rating for a pet collar or for a keyring that might get exposed to extreme conditions.
