Needed some more velcro key tags for my keys at work. These hang on a a 8.5x11 piece of plastic that has velcro strips on it. The key tags have the mating piece of velcro which allows them to stick to the plastic for organizing your keys. I needed some more tags so I made some. Put a piece of velcro on the back and you're good to go. Key rings can be found almost anywhere.
