I cut my own and a few for others from a sheet of material that came in a old Mainstay brand cd binder. The very light grain looks better than OEM slick and glossy material in my opinion.
A correct reproduction is a special material. For the life of me I can't remember what that stuff is called ( and I CNC machined a mile of it ). Anyway... Correct would have the little rib formed on both edges. Makes it better but much more expensive to produce too.
