These are curtains from Nitori. I ordered too many, and they are unopened. They have a gap-blocking specification. I use the same curtains at home, and they are refreshing and provide excellent blackout. The following is quoted from the sales page: ● Adjustable hooks to adjust the length. ● Blackout Grade 1: Blackout rate of 99.99% or more (JIS standard blackout level. There are blackout levels 1-3, with level 1 having the highest blackout rate.) ● Blackout Level 5 (Nitori's blackout level. There are 5 levels from 1 to 5, with higher numbers indicating less light penetration.) ● Magnetic closure to prevent gaps in the center (at the hem) ● Special hooks to reduce gaps on the sides (Depending on the shape and installation of the curtain rail, the special hooks may not be able to be attached) ● Shape-memory processing for beautiful pleats even after washing ● Soundproofing effect: Resin coating on the back of the fabric reduces sound leakage from the room and reduces noise from inside or outside the room. ● Heat insulation effect: Blocks outside air and prevents the room's air from escaping. ● Heat insulation rate: 60.7% ● Heat retention rate: 34.3% ● Machine washable at home. ● 1.5 times pleats
