Over 'n' Over Reusable Self-Stick Etching Stencil for Glass (or Stamping) - BUNDLE OF THREE BLANKS - Make Your Own Designs!

Used these to etch rocks glasses with a city skyline. Held up really well being rinsed and reused on 16 glasses. Given the price, I thought they'd be larger. So I had to split the design across 2 sheets. (Yes, I know it says the size way down at the bottom of the details but I didn't get that far originally lol)

Good

Kind of hard to use, not a lot of sticking power
