This is a futon cover custom-made with fabric purchased at Shinjuku Actus. It has been stored at home unused as I switched to a bed. You can open the zipper on the side and slip your futon in. Size: 100cm x 200cm (over 4m of fabric used) The fabric is 100% cotton. It has a firm, thick texture with a feel similar to linen. As it was custom-made with high-quality fabric, it turned out to be a luxurious cover. There is a 140cm zipper opening on the side. Although it was made as a futon cover, due to the thick fabric, I think it would also be good to use it as a sheet, reversible. It is new and unused, with no stains, fading, etc., and is in good condition, but I have priced it as is because it has been stored for a long time. Please review the above along with the photos and consider purchasing if you are satisfied.
