Unique Design Stacking Tower - Unlike traditional stacking cups, stacking rings, stacking rocks and rainbow stacking toys, the stacking block toys are made up of six different sized trapezoidal hexagons that can even become curved towers as the stacking direction changes. HIGH QUALITY MATERIALS - The stacking toy is made of high quality ABS material and BPA free silicone with rounded edges and a burr-free surface. Two stacking blocks can be used as teether toys. GET YOUR BABY'S ATTENTION - The baby building block toy contains two rusted parts that no baby can hold their attention. It's also a great way to turn your baby's crying into a laugh. Learning and Educational Toys - Each baby's sensory toys are different in color, size and touch and can enhance your child's cognitive abilities. What's more, babies can develop their hand-eye coordination and thinking skills to explore different stacking styles.
