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 and Remain Flat Over Time! They also add protection to your target faces from becoming damaged, dirty and black - without taking away from the speed by being too thick. Thicker is not better - Other target decals that are made of "Foam" and thick can take damage by the ball impacting it from the sides.
Targets already have a foam impact point built into the target assembly itself.
These are covered with 5 mil Mylar for Extreme Durability and a Super Great Shine.
Fantastic Improvement to your Machine !!!
