A polyester (Mylar® type) material for small-character stencils (under 1/4″) and fine-detail cuts. Produces superior paint masking; holds tightly, yet releases clean. Made of 3-mil matte polyester bonded to our ultra-removable/repositionable light-tack adhesive on a clear backing. Poly-Cut™ is popular for glass etching, paint masking, epoxy-stencil marking, and any masking project where sharp, clear, non-stretched lines are required. Comes on a 6″ core.
