Colors, Counting, and So Much Stacking!One, two, three…weee! The 7-piece Imaginarium Stacking Cups set is perfect for little ones developing their fine motor skills and hand-eye coordination while learning colors and counting, too. Let your little ones feel and play with stacking cups of different sizes, in fun colors that can teach them all about special awareness and cause and effect. Once they've stacked all of their cup's way up high, they can place a cute friend at the top…or knock them all over and start stacking them again! Each stacking cup is made from wheat straw materials to keep our world in great shape for your little ones when they grow up.
