The Geometric Rattle includes one round yellow ball with joyful face detail that contains a wooden bead, one pink cylindrical rattle that contains a bell, and one square toy that contains plastic beads and a colored lens that children can look through. Expertly designed sizes and shapes that are a perfect fit for little hands. The Geometric Rattle Trio's combination of soft colors, smooth surfaces and interesting sounds give babies a fun and highly sensory playing experience. Shake to entertain your baby with the sounds that the different shapes emit.
