Made in Japan, Flame-Retardant, Blackout Curtains - Set of 2 Size: Approximately 175 cm (height) x 146 cm (width) Color: Royal Blue, a deep blue with a glossy, smooth texture Thank you for viewing. I purchased these curtains from Rakuten approximately 3 years ago. I don't have the purchase history, so I'm unsure of the exact blackout rating, but I chose the best available option for use in a bedroom, so I believe they are either Grade 1 blackout or completely blackout. Even when closed during a sunny day, the light that leaks through the gaps is quite bright. They are flame-retardant, so you can feel safe in the event of a fire. They are in overall good condition. I have home-cleaned them once every six months, and since they were hung on a well-ventilated window, I don't think there's any noticeable dirt. The tassels were only hung and never used. I am selling them because the windows in my new home are not suitable for these curtains.
