These high-quality stencils are laser-cut from durable oil board (compressed, oil-treated cardboard made specifically for stenciling), so they can be used multiple times! This set includes 6 separate stencils, each a different size. Letter heights range from 2 inches down to 0.50 inch. We also include a 2-page printed how-to sheet with tips, tricks and advice for making the best use of your stencils. These are not self-adhesive; we recommend using a repositionable spray mount adhesive to help hold them in place. Stencils may have slight residue on cut edges left over from laser cutting process, which does not affect their performance.
