Thank you for viewing! :-) I purchased this new and used it for about 3 months. There are no air leaks. I don't see any noticeable stains, but there might be some water spots, so please refrain from purchasing if you are concerned. Only the items in the photos are included, and there is no cardboard box, so I will flatten it and ship it via Yu-Packet Post. To prevent any problems, please ask any questions before purchasing.
