These are not made of cheap thin vinyl and will not stretch or wear easily. They are hand made under a very difficult and expensive process and are all custom die cut. The back of the decals have a center cut indentation which allows the sticker to rest smoothly over the rivet. They also add extra protection to your targets and allow the ball to have a more "softened" hit. The decals are covered with 5 mil mylar for extreme durability and a great shine. A Great Improvement to your Machine!
