These curtains were only used once for a trial and are in almost new, very clean condition. They are Grade 1 blackout curtains, which effectively block out light, and they also have excellent functions such as heat shielding, heat retention, obscuring, and UV cut, making them very convenient to use. I had no complaints during the trial use. I have since purchased and am using the same series in the correct size, and I am very satisfied with the color and functionality. The size is 100 x 110cm, and the color is green, a set of 4 curtains (2 of each). Recommended for those who want to prioritize both functionality and appearance!
