This is the main product, which normally only includes one mattress pad, but I am including two extra ones. They are not waterproof mattress pads. In my subjective assessment, the mattress pads have no stains, wrinkles, or fraying. I purchased this in 2023. I used it a few times, and in my subjective assessment, there are no noticeable stains, but there is some loose thread. If you'd like, I can cut off the loose thread before shipping. Also, I have washed it at home (with baby detergent), so there are wrinkles. The inner packaging is not the original bag; it is a household 45-liter size bag. The outer box is also torn. The instruction manual is included. Please check my profile for information on shipping and storage.
