Set of 3 design buttons: Hello Kitty, Anpanman, and Baikinman. Made of plastic. Anpanman and Baikinman are approximately 1.8cm in diameter, and Hello Kitty is about 2.5 x 1.8cm. Although new, they have been stored at home for a long time. My child's preferences changed so quickly, and I missed the opportunity to use them. Thank you. - Design: Hello Kitty, Anpanman, and Baikinman buttons - Quantity: Set of 3 - Material: Plastic Thank you for looking.
