You need only buy these stencils once they are Virtually Indestructible.

Airbrush Bodyart Stencils.
These stencils are not the stick-on disposable type.
These stencils are so much cheaper and better quality than all the rest.  They are
made using high quality materials and are the best on the market.  They have a
long life, and if cared for correctly can be reused thousands of times over. You
only need to buy them once. These stencils are specifically designed for
temporary tattoos and airbrush face painting and can be used for any other stencil
job.  Simple to use and are made of strong, durable .30mm flexible Vynalaser.
They can be cleaned off easily with solvents. You can let your imagination run
wild!!

I only have (1) of each design so please do not delay in purchasing if you are
interested.  I am selling an overstock from a set I personally bought to use from
Airbrush Body Art.
