Cotton: 100% This is a queen size. It's popular and already sold out online. This is a smooth, plain white fabric often used in hotels, and it's a 100% cotton sheet. I think it's clean because it hasn't been used much. It has been cleaned. Shipping from Okinawa Prefecture, so it may take a little time to arrive ^_^ ◉ Returns, refunds, and complaints are not accepted, so please purchase with understanding. ◉ Please feel free to ask any questions ☆
