They are reusable airbrush stencils allowing for dozens of uses. Spray using water-based paint and clean with a soft brush, alcohol, and water. 

 Another important aspect of these templates is that they bend better on curved and irregular surfaces than any other type of stencil. This allows you to confidently take on jobs that other artists will simply pass because of their difficulty.
