We currently offer three materials: 14 mil mylar plastic, 7 mil matte adhesive, and 0.6mm metal. 14 mil mylar is durable and flexible. It works for a wide range of applications and is good for hundreds to thousands of uses. 7 mil matte adhesive comes on a paper backing and can only be guaranteed for a single use. Sometimes it can be used multiple times depending on the complexity of the design. It has a high-tack adhesive, so it holds tightly on surfaces to achieve high levels of detail. And the adhesive doesn't leave any residue on the surfaces it touches. Our metal stencils are by far the most durable option. They're best for signage, stand alone artwork or extra durability while stenciling. We cut them from 0.6mm stainless steel and they're significantly more stiff and heavier than our other stencil materials.
