Bad Ass Stencils are one of the most popular lines of airbrush stencils used by artists worldwide. Each stencil was intricately designed by award-winning makeup artist and body painter Andrea O'Donnell. These professional airbrush tools can easily be utilized in a multitude of applications on various surfaces...using a wide variety of mediums and tools. Each individual sheet consists of a combination of several stencils that include thematically related design elements, patterns, textures, and artistic edges. The possibilities of each design are limited only by the artist's own creativity. Bad Ass Stencils are made of a durable yet flexible 7 mil mylar plastic. The material is medium-weight and about the thickness of card-stock. The material is thin and flexible enough to achieve outstanding detail when stenciling... yet strong enough to clean and use many times. The material is solvent-proof.
