Instant purchase OK! How about this to protect against yellow sand, pollen, and dust? I opened it, but it's unused. I'm selling it because I don't use it. Please understand that this is a used item that has been stored at home for a long time. There are no instructions for the material or function, and the size etc. are also unknown. Please refrain from asking questions. I plan to ship it folded in half via Yu-Packet Post. If you want to put away the laundry drying cover each time, consider the sheet type. You just put the sheet over the laundry and secure it with clothespins, so it doesn't take much effort to set up or remove. The sheet type is also attractive because it easily hides clothes. Compared to other types, it covers a wider area and is more likely to hide everything, making it suitable for drying underwear and laundry with names on it. Thank you.
