Thank you for viewing my listing among many others!! [Online Retail Price] 5,280 yen [Color] Ice Gray [Size] Width 150 x Length 178 cm [Class 1 Blackout] These curtains have a blackout level of 99.99% or higher, allowing very little external light to pass through. This means you can make your room so dark during the day with the curtains closed that you can barely make out the other person's facial expressions. Even within the same class, the degree of blackout can vary depending on the brightness and color of the curtains. Light, pale colors tend to let more light through, while dark, deep colors are more effective at blocking light. If blackout performance is your priority, we recommend darker colors. [About the Fabric] These curtains are made from 100% polyester, thick fabric. They have a soft, smooth texture and a matte finish. The fabric is highly functional, offering Class 1 blackout, heat shielding, heat retention, and soundproofing. The front and back of the fabric are the same color, making them easy to use as dividers. [Suitable for All Seasons] Because the fabric of these blackout curtains is densely woven, it is also a great advantage that they are resistant to heat and cold. They prevent room temperatures from rising in the summer and dropping in the winter, improving the efficiency of your heating and cooling. If you have a room with strong west-facing sunlight, installing blackout curtains can also help you save on your monthly electricity bills. [Triple Weave Technology] The fabric utilizes triple-layer technology, weaving in black threads to provide excellent blackout functionality. These thick blackout curtains are equipped with a function that effectively blocks sunlight and UV rays from outside. *There are some stains, but they are likely removable by washing. *Please note that the outer box may have scratches or dirt.
