Blackout, Heat-Insulating, and Soundproof Curtains (Lilac Ivory) Used on a frequently opened window for ventilation, so there are some minor stains. The stains I found are shown in photos 5-10. The stain in photo 10 looks a bit like a spot. It's not very noticeable, and the fabric has a sheen, so it's not very clear. They can be washed, so I think the stains can probably all be removed. *Curtain tassels are not included.* Used for about 1.5 years. The blackout function is perfect! If anyone is interested, please consider them. ☺︎
