Set of four: This is a set of four clear, non-adhesive, durable wire shelf liners. Perfect for a four-tiered wire shelving unit, pantry, closet or multiple drawers and cabinets. They will create a flat, smooth surface on wire shelves. Sturdy material for wire shelving: This wire shelf liner is sturdy to prevent items from tipping over and falling through the gaps in wire shelving. Additionally, the smooth, sturdy surface ensures that clothing will not be indented by wire shelving. The solid shelf liner is waterproof, preventing liquid and solid spills and dust from falling on lower shelves. Other uses: This shelf liner was not designed just for wire shelving: the bubbled texture on one side and smooth top allow for use as a traditional shelf liner in drawers and cabinets to prevent slipping. The textured side can be placed down or up, depending on your preference. Use: Unroll the shelf liner and place on shelves. Easily cut the liner to size with regular scissors if you need a smaller size. If the liner rolls up at the edges, place heavy objects at the corners or roll the liner the opposite way for several hours. To clean, wipe off with water only or use mild soap for tougher spills. The liner is easily removable to clean. Size & material: Each liner is 18” x 48” (45 x 120 cm) and 0.5 mm thick EVA. There are a total of 4 pieces of liner that are each 18” x 48” for a combined total of 24 square feet.
