Unused item. It's quite old, so I opened it to check the contents. It's in beautiful condition, with no noticeable stains. Please refer to the photos for the size. The depth is about 13cm. Color: Dark gray Load capacity: Approximately 10kg, made of sturdy, thick material (I believe it's polyester). I will put it back in the original bag with the instructions and fold it to ship via Yu-Packet Post. Please refrain from purchasing if you are concerned about minor details, as it has been stored at home.
