Thank you for viewing my listing among many others!! [Online Sales Price] 3,480 yen [Color] Ice Gray [Size] Width 100 x Length 140 cm [First-Class Blackout] These curtains have a blackout level of 99.99% or higher, allowing almost no external light to pass through. This means you can darken your room to the extent that you can't discern facial expressions of others when the curtains are closed during the day. Even within the same blackout class, the degree of light blocking can vary depending on the brightness and color of the curtains. Light colors tend to let more light through, while dark colors are more effective at blocking light. For those who prioritize blackout performance, darker colors are recommended. [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 first-class 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] Due to the high density of the fabric, blackout curtains are also excellent at blocking 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 systems. Installing blackout curtains in rooms with strong western sunlight can also lead to savings on your monthly electricity bills. [Triple Weave Technology] The fabric utilizes triple-layer 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.
