Yes because plastic stencils have a longer life than pre-cut oil board sheets. Oil boards are oil treated paper with the usual thickness ranging between .010” to .015". ABS plastic stencils that we offer are 63 mil (1/16") thick and last at least 2+ years in outdoor conditions. With oil board sheets, you can make only a limited number of impressions because they quickly become sodden. Plastic stencils are reusable and can be used for unlimited times. Inside of the plastic stencil is polished, and burr-free for a clean application.
