I received this as a baby shower gift. I've used it about twice, and there are no noticeable stains. There is a slight discoloration in some areas (see photo 4). I've stored it in a bag. Please refrain from purchasing if you are sensitive to used items, as this is stored by a private individual. swimava Swimava Neck ring Size: Regular size (18 months and 11kg) Color: Monotone Penguin Japanese official guide included All accessories are shown in the photos.
