This is a set of two KEYUCA order-made lace curtains. These are KEYUCA's original lace curtains that overcome the disadvantages of high UV protection. They can be used as a pair of curtains that open from the center. The product is listed on the following website page: https://www.keyuca.com/Form/Product/ProductDetail.aspx?shop=0&pid=7200147&cat=410001002 ・Style: Flat / 2-mountain, 1.5x folds / 3-mountain, 2x folds ・Functions: UV cut / Washable / Heat insulation / Privacy protection / Light transmission ・Composition: 100% Polyester ・Size: W=4,980mm H=2,120mm ✳︎W is the combined width of the two curtains ・In particular, there are no noticeable stains. I recently ordered these, and while the light transmission is excellent, they lack transparency and didn't match my expectations, so I am selling them. Please feel free to contact me if you have any questions.
