It's a gray size M. I've used it about 4 or 5 times. There are no noticeable stains, and I think it's in relatively good condition. Length: Approximately 56.5cm Width: Approximately 53cm There may be some slight variations. Please examine the photos carefully and make your purchase only if you are satisfied. It will be folded and compressed for shipping. Due to the thickness, it's difficult to combine it with other items.
