Stencil Definiton, Oxford Languages:
"A thin sheet of cardboard, plastic, or metal with a pattern or letters cut out of it, used to produce the cut design on the surface below by the application of ink or paint through the holes."

I created these basic stencils because we needed those stencils at work to mark the company trucks, but we didn't feel like paying 19500 Uruguayan Pesos (487.5 US Dollars as of 07/05/2023) for professional-made stencils.
