Width 25-35cm. Length 100cm. These curtains are brand new, but the size didn't fit, so they look like they do in the photo. I opened the package, attached the curtain hooks, and used them once, but they didn't fit, so I put them back in the bag and they are still in good condition! They have blackout and thermal insulation functions. They cost 4960 yen for two, but I'll sell them for 2100 yen!
