Waterproof Sheet Single 100 x 200cm It has been used, so the elastic is stretched. You may want to replace it, or you might not feel it shift much if you continue to use it as is. Please check the photos. The star pattern looks worn, but I think that's probably the original design. (Sorry if it's due to deterioration) Please understand this fully before considering a purchase. Used item. Washed. Price not negotiable.
