With the loop sticker attached to the hook on your metal ID, test where you would like to attach to your watch. Make sure a first responder would easily see the tab of the metal ID extending out from your watch. Then, make sure the back of your watch is clean and dry. With the loop sticker still attached to the hook, peel off the release paper from the back of the loop sticker and press onto the back of your watch. DO NOT attempt to separate the hook & loop — it may take up to 24 hours for the adhesives to bond properly to your metal ID and watch.
