I am selling this item because I accidentally purchased the wrong size. I opened it because I intended to use it, but I realized the size was wrong immediately, so it is new and unused. I can't use it, so I'm really in trouble. Thank you. This is a waterproof box sheet with a high level of waterproof performance, featuring a polyurethane coating. ■ Family 240cm Width 240cm × Length 200cm × Height 30cm Material/Specifications Surface Pile: 100% Cotton (Sinkers Pile) Surface Ground: 100% Polyester Back: Polyurethane Coating All-around elastic - Color: Charcoal Gray - Waterproof Function: High waterproof performance Thank you for viewing.
