Warm Company Insul-Bright Insulated Lining, 22.5 Inch x 3 Yards

An insulated lining made of polyester fibers needle-punched through a reflective metalized film, sold as one 22.5-inch wide, 3-yard piece cut from the bolt. The film reflects heat or cold back toward its source, which suits pot holders, oven mitts and casserole covers. It will not shrink, needs no pre-washing, and is not recommended for microwave use.
