Make your competition disappear in the rear view with the Black round Metal Keychain! While the product does measure 1.4″ x 2.9″ including the keyring, it does not function as a can opener. The black colored, round metal key tag does function as a laser engraved or blank talking point for your company at auto shows, conventions and trade shows. Get a jump on your rival companies in the promotions department as you drive the hordes of new customers in your direction first!
