I purchased and used this five years ago. It was kept in a room and wasn't used much, so I don't think there's much noticeable dirt inside. There are scratches on the back of the buckles on both the left and right sides of the exterior. They don't show up well in the photos, but there are some scratches on the plastic part of the top. Width: 36.5cm, Depth: 57cm, Height: 36.5cm This is a size M. Please understand that this is a used item.
