This is a gift from Yamaha Music School that my child received during infancy. It's unused and has been stored at home, so I've marked it as "Like New" instead of "Brand New" just to be safe. The zipper works well and is designed to be easy to open and close, even for young children with weak finger strength. There are no tears, frays, or stains. Please check the photos with the water bottle for the size. It will be folded in half for shipping. Thank you for your understanding. Thank you for looking.
