Thank you for viewing my listing among many others!! [Online Sales Price] 3,280 yen [Color] Gray [Size] Width 100 x Length 135 cm [Grade 1 Blackout] These curtains have a blackout level of 99.99% or higher, allowing almost no light to pass through from the outside. This means you can darken your room to the extent that you can't discern facial expressions even during the day when the curtains are closed. Even within the same grade, the degree of blackout varies depending on the brightness and color of the curtains. Light, pale colors tend to let light through, while dark, deep colors are more resistant to light. If you prioritize blackout performance, 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 Grade 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 blackout curtains are made of high-density fabric, they are also excellent at preventing heat and cold from passing through. They prevent room temperature from rising in the summer and dropping in the winter, improving the efficiency of heating and cooling. Installing blackout curtains in rooms with strong west-facing sunlight can also be expected to save on monthly electricity bills. [Triple Weave Technology] The fabric utilizes triple-structure technology, incorporating black threads into the weave, which provides excellent blackout functionality. These thick blackout curtains are equipped with a function that effectively blocks sunlight and UV rays from outside. *Please note that the outer box may have scratches or dirt.
