- Material: 100% Cotton - Size: 140cm x 240cm - Type: Flat Sheet This is a long-size flat sheet for a futon. It is labeled as pre-shrunk. It was a gift and has been stored at home for a long time, but it is in beautiful condition with no noticeable yellowing, stains, or spots. I will take it out of the box, fold it compactly, and ship it in simple packaging. How about a plain weave flat sheet for your home or for guests? I will ship it promptly via anonymous postal service!
