I purchased these about four years ago. They are high-performance curtains with blackout, heat-blocking, and soundproofing features. They are in good condition, with only minor imperfections that are barely noticeable. However, please be aware that I am not a professional inspector, so there may be small stains or other minor issues. I believe they cost around 6,000 yen when I bought them. The following is a quote from the Nitori website: ----------- Adjustable hooks allow for length adjustment. (A-hook specification for beautiful drapes) Grade 1 blackout: 99.99% or more blackout rate (JIS standard blackout level. There are grades 1-3, with grade 1 having the highest blackout rate.) Blackout level 5 (Nitori standard blackout level. There are 5 levels, from 1 to 5, with higher numbers indicating less light transmission.) Heat-blocking effect: Blocks outside air and prevents room air from escaping. Soundproofing effect: Resin coating on the back of the fabric reduces sound leakage from inside and reduces outside noise. Shape-memory processing keeps the pleats looking beautiful even after washing. Machine washable.
