The peel and stick Hook Backings also known as hook and loops come in 5 pack and measure 4x2 inches.
You can stick it on the back of a patch (patch must have a plastic backing on it).
The strips are made in USA. Glue is strong and our testing makes this a viable option to turn an iron on patch to a hook and loop system patch.
Please note the loop fabric that goes over your jacket is sold separately. They also have peel and stick backing but they must be sewn on to your clothing. The peel and stick backing means you can attach the loop fabrics to the bumper of your car or your window or door and stick on any patch to it.
