Set of two curtains, each measuring 100cm wide (approximately 120cm when laid flat) x 198cm high. I am sorry, I do not know the detailed functional specifications. However, I believe it is quite difficult to see through from the other side. You can vaguely see the outline of light, but it's difficult to make out fine details. These are simple lace curtains. As shown in the fourth image, there is some staining on the back. The front has been inspected by an amateur, and while there are a few loose threads, there appear to be no major scratches or stains. They have been washed and stored for a while, so there are some wrinkles. There is no strong odor, but please be aware of the wrinkles. Thank you!
