Thank you for viewing my listing among many others!! [Online Retail Price] 4,280 yen [Color] Brown [Size] Width 100 x Length 190 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 point where you can't discern facial expressions even when the curtains are closed during the day. While the blackout level is the same for this grade, the degree of light blocking 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. 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 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] A significant advantage of blackout curtains is that their high-density fabric makes it difficult for heat and cold to pass through. 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 that receive strong west-facing 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 are thick blackout curtains that effectively block sunlight and UV rays from outside. * Opened but unused, in beautiful condition.
