Plast-O-Mat® Ribbed Shelf Liner™ cushions and protects better because it's five times thicker than similar products. The ribbed texture allows air to circulate, preventing molding, mildewing and odor retention. Our Ribbed Shelf Liner™ is available in three convenient widths. The 12" width fits most standard upper kitchen cabinets. Use the 24" width for lining deeper shelves, cupboards and drawers as well as in cabinets and under sinks. Plast-O-Mat® can easily be cut with standard household scissors to fit any space.||Made from polyethylene, Plast-O-Mat® is 100% recyclable
