I washed it twice. It's a thin fabric. I switched to a terry cloth one and have been storing this since I stopped using it. It's a shape that's difficult to fold, so please be aware that it may not be possible to fold it neatly when shipping. [Size] Queen: 165x215cm (All-around elastic, 30cm deep pocket! Suitable for thin futons, and fits snugly over thick futons) [Specifications] The sheet has elastic all the way around to prevent slipping, making it easy for even one person to put it on neatly. With the anti-slip elastic, it can be used for folding mattresses and futons, and in various other places. It's also easy to put on and take off. You don't have to worry even if you toss and turn at night. Sheets with anti-slip elastic are very convenient these days. I recommend you try them. [Fabric] Made of a blend of 50% cotton and 50% polyester, it has excellent quick-drying properties, so it dries quickly and is easy to wash! It's also easy to care for because it doesn't wrinkle easily after washing! So you can always keep the cover clean and sleep comfortably every day. It has a fine "peach skin finish," so it's very soft and feels good against the skin. It's odorless and non-toxic, so even children can use it with ease. [Color and Size] Solid colors that are easy to match with your room's interior, changing with the seasons. [Washable]: I think you want to use sheets that are always clean, as they touch your bare skin every day. You can use it for a long time throughout the four seasons. It has excellent quick-drying properties, so it dries quickly and makes washing easy! It's also easy to care for because it doesn't wrinkle easily after washing!
