I've been using this pickguard on a Squier by Fender SONIC MUSTANG HH for about six months. The condition is good. (Unopened mounting screws are included) It was possible to replace it without modification from the original pickguard. (Modifications may be necessary depending on the individual guitar) Made of plastic, 2.0-2.2mm thick. It originally had aluminum foil shielding on the back. I don't smoke. I don't have any pets.
