The six colors of Irotchi come in small, medium, and large sizes, and can be nested like Matryoshka dolls in sets of three. While playing, children will naturally notice differences in color, shape, and size. This is a used item that has been played with by a child, so there may be minor scratches. Please understand that this is a used item before purchasing. I am also selling other Irotchi goods, so please consider them as well. If you would like to purchase multiple items, please request a combined purchase. Individual sales are not possible.
