ID Tube is a great way to pass along the pertinent information on your pet should you become separated. Compact metal tube unscrews to hide paper containing your name and address inside. Metal tube resists the elements, assuring that your pet's information stays safe and dry inside. Information can only be accessed by opening the tube, keeping your name and address information private until it's needed. No more advertising your name, address, and phone number when you walk your pet. Attaches to d-ring on any pet's collar.
