Use them to mark parking space assignment, building numbers, and containers. All stencils are made of 1/10" thick semi-rigid plastic and can be used over and over again. Our stencils are better than the competitors because the material is specially formulated for pavement stencils so it weighs a little more and lays flatter. This helps prevent under-spray. This is not an off the shelf plastic, the pavement stencil material has a specific resin, produced at exact specifications, so it is virtually waveless and has a very smooth surface. These properties make the stencil lay flatter and clean up easily.
