Thank you for viewing. Brand: Sanrio Characters: Badtz-Maru, Hanamaru Size: 20cm tall, 19cm wide The whistle sounds when you press the belly firmly. This is a product from about 25 years ago. It has been stored at home, so there may be some deterioration, but I think it is in generally good condition. I believe there are individual differences in how things are perceived, so I would appreciate it if you could purchase it only if you understand. Thank you.
