I purchased this at the Disney Store. I used it once when I went out, and then I washed, disinfected, and stored it. I'm selling it because I don't have a chance to use it. It got scratched in my bag when I carried it around. Please check the photos. There's no problem at all with using it, but please refrain from purchasing if you are concerned m(_ _)m The bottom has a removable cover! It's made of silicone and is non-slip.
