Baboon to the Moon Small Go Backpack in Cotton Candy Pink The bag has never been used. However, the pink has some blue spots throughout. I am not sure if there is something behind the pink nylon or if the pink nylon is dyed in spots, but I believe it is a manufacturer defect. It might not be noticeable once the backpack is full but I am not sure. Easy to clean and has a waterproof outer shell.
