This is the brass hand tool that keeps you from coming into direct contact with the dozens of contaminated surfaces you encounter every day. When used correctly, the key-shaped tool lets you grasp door pulls, sign your name on a tablet, and press elevator buttons and keypads without your hand or fingers touching them. It's made from uncoated brass with 60% copper content that has been proven in laboratory tests to inhibit the growth of harmful bacteria on its surface. Attaches to keychain. 33/4" L x 11/2" W x 1/4" D. (6 oz.)
