Thank you for your interest. This is a sticker I received a few years ago at the Sony Store Ginza. I believe I received it during an event. Size: Approximately 10 cm in diameter. Please understand that there may be slight variations. I think it's rare and valuable now. I don't think it's widely available as it's not for sale. How about it for aibo collectors or those who are raising them as pets? Thank you. aibo is a dog-shaped pet robot developed by Sony. It is characterized by learning personality and behavior and growing through communication with humans. Features: Autonomous robot that mimics the ecology and behavior of dogs. Uses AI technology to recognize owners and understand the environment. Personality and behavioral patterns change through communication.
