Made out of a food safe plastic called Mylar that is 10 mils thick(0.010 inches). It is thin, flexible, and reusable. Great for airbrushing, gently tracing a design onto your sweet treats, or dusting the design with powdered sugar/edible glitter luster onto a different surface but may have many other possible applications. Will be cut using a laser printer at the time of purchase. Laser allows for fine cut details to providing unique, intricate design. Will come in white. Some intricate designs require the laser to remain in areas longer than others, because of this certain stencils may come with the design edges tinted yellow/dark brown from the heat of the laser. Sizes pertain to ENTIRE design’s height (top to bottom) or length (left to right). Material will be approx. 1 - 1 ½ in longer than the design. Displayed is our 4 inch size (meaning the design measures 4 inches at the longest side of the design with the stencil itself being 5 ½ inches x 5 inches). All other sizes are directly proportional to this size. NOT dishwasher safe. SOAK IN WARM WATER WITH DISH SOAP THEN GENTLY RINSE WITH COLD WATER. LET DRY THOROUGHLY BEFORE USING AGAIN. Prolonged exposure to direct heat/sunlight should be avoided. Store on flat surface to prevent bending/warping. Larger sizes will be shipped in rolls and may arrive slightly curled. To flatten your stencil, we recommend placing it on a flat surface with a heavier, flat object on top (such as books or an area rug) and leaving it overnight.
