Here's Duncan's Butterfly Mini Yo-yo (*^^*) It's one of the items in the World's Smallest collection, about 3cm in diameter, and very cute♪ It has metal weights inside, so it has some weight and can be played with as a yo-yo. How about it for collectors (^ー^*) I'm also selling Beyblades and yo-yos, so I'm looking forward to combined purchases(^^ ) WORLD'S SMALLEST Mini Surprise Toy Miniature Toy Mini Yo-yo Hand Spinner Metal Fight Kendama Spinning Top Mini 4WD Spin Gear Hyper Yo-yo Plastic Model
