I purchased this new on Amazon and used it as a mosquito net only during the summer. The price, as it's currently out of stock, is not entirely clear, but I believe it was around 18,000 yen. It's a type that can be fully closed, opened, or used as mesh. The product is very good, but it's a bit large for my home, so I'm selling it. I have washed it at home. Being fabric, please understand that some small lint, as shown in the photos, may have adhered to it due to washing. It's navy blue, so it provides a certain degree of darkness, but the fabric is not thick, so it's not 100% blackout. There are also some small holes, about the size of a pinprick. Being fabric, it's not particularly sturdy. Please only purchase if you understand this. As mentioned in the Amazon reviews, the top frame sticks out slightly. This seems to be part of the design. There's no problem with its use, but if you're concerned, please refrain from purchasing. It will be simply packaged in a Yamato cardboard sheet.
