Black, no markings. It's quite long. There's some soiling, but up to about 50cm from the area in the photos, the inside is a solid black and no soiling is visible. I haven't spread it out completely because it's long, but I think it's fine. I'm selling this because I found some thin fabric while organizing my dresser. In the 8th photo, you can see how the fabric is slightly transparent. I'm selling two rolls, and the texture is very nice. There are a few stains on the outside. I think the stains can be removed. Thank you for looking.
