I haven't used this after purchasing it. I'm selling it to declutter. Please confirm the size in the third image before purchasing (^^) Also, if you're worried about initial defects, I have an electric air pump, so I can inflate it once to check for holes before shipping. Please contact me via message or comment. I have two of these since I have two children. Please contact me if you'd like to buy multiple items. I'm also selling other patterns.
