Thank you for finding this! (^_^) I purchased this from the Benesse online store "Sukku." It's a shape and size that's easy for children to hold. See the third photo for a size comparison with an adult hand. When my child was in the lower grades of elementary school, it was very useful when friends came over to play. It's durable and doesn't break easily, and there are three colors, so there's no mistaking them with friends' (^_^) Thank you! ( ´ ▽ ` )
