Children's muffler, My Melody, Sanrio Used less than 10 times as I mainly used other mufflers. It's easy for children to use, as you just put it through the hole. When I home-cleaned it, part of My Melody's ears started to come off from the glue, but I don't think it affects the use (see photo 4). For those who don't mind the details as it is a used item.
