Pet Safety Tags are the perfect gift for your companion animal! They're great for taking nighttime walks while keeping both you and your pet safe! Each piece is equipped with a lobster claw clasp that will attach the safety tag securely to your pet's collar or even your belt, backpack, or keychain. Pet safety tags turn on with a master on/off switch, located on the side of the unit. Once the unit is switched "on", it is light and motion activated. When it becomes dark enough, the safety tag will automatically illuminate with the movement of yourself or your pet. This is an excellent safety item and would also make a wonderful gift.
