I couldn't find this item in the store, so I purchased it online from Nitori. However, it didn't match my expectations, so I'm selling it. I only took it out of the package and unfolded it to check it. I haven't even put it on a futon. It's difficult to put it back in the package once it's out, so I will fold it and ship it via anonymous delivery. The following is a quote from the online site: ■■Nitori Official Website■■ Gentle watercolor floral pattern. Uses 100% cotton fabric with a good feel against the skin. 100% Cotton Single Size 【NITORI×TEIJIN】 ● Uses "Nanofront®" fabric on the top and bottom of the reverse side to prevent the futon from slipping. ● Easy to change the cover because it's string-free! ● Easy to put in and take out! Full-open zipper ● Easy to attach and detach with slits ■ Number of threads (approx.): 180 threads Outer fabric: 180 threads, Inner fabric: 180 threads * "Number of threads" refers to the total number of "warp threads" and "weft threads" per inch (2.54cm). The higher the number, the finer the yarn is used, resulting in a softer and finer fabric. Fabrics with 250 or more threads are considered high-density fabrics. ■ Composition Side fabric: 100% cotton Non-slip part (inside): 100% polyester ■ Machine washable (use a net) This is only a duvet cover for sale.
