12-Piece Number Stencil Sets. Stencils have a variety of uses whether it may be property identification or just simply parking lot traffic control. Stencils are constructed with 1/10″ durable, flexible orthopedic grade plastic that will last for years and precision cut with a router. Paint can be applied by using spray equipment, brush or a roller. Stencils are reusable and cleaning is easy, simply bend or hit the stencil against a hard surface when paint is dry and the paint will flake off.
