BAM stencils or Bad Ass Mini stencils are reusable mylar stencils. They are great for airbrush and for regular face paint. When using a sponge, make sure your sponge is not too wet, and that you have enough paint to make a clear impression. Buy face paint stencils online at the Face Painting Supplies CA online store. We offer Bad Ass stencils, Half Ass stencils & other face painting stencils. Bad Ass Stencils are made of durable yet flexible 7 mil mylar, a medium weight material as thick as card stock. This material is thin enough to achieve outstanding detail when stenciling, yet strong enough to clean and use many, many times and is solvent proof.
