One has lost the valve cap on one side. (See images 4 and 5) Because it's the valve for inflating the first level, there's no problem when using levels 1 or 2. When using all 3 levels, the first level tends to deflate easily. Both have no noticeable stains or scratches. Thank you for viewing. Available for immediate purchase.
