1.[Stacking and Spinning Toy] The stacking spinning toy is simple and creative in design, consisting of a screw rod and rainbow-colored wheels, which your child can use to spin the discs to the ground. Each disc is available in two colors and can be rotated arbitrarily, which is very suitable for toddlers over 1 year old. 2.[Endless hours of fun] The discs can be stacked by size, color, shape or randomly; when the stacking is completed, pull the rod out of the base and watch all the discs slowly spin and fall to the ground; flip the base to choose to shake or fix; or, you can hold both ends of the rod and let the discs spin up and down endlessly. 3.[Brain Development Learning] This toddler spinning toy is not only fun, but also a great learning toy for young children. It helps to develop hand-eye coordination, cause and effect learning, dexterity and fine motor skills during play. Toddlers can also practice color recognition and tactile exploration. 4.[And safe] The rotating stacking toy is made of sturdy and durable ABS plastic, which is durable, comfortable to touch, BPA-free, and has passed rigorous toy testing to ensure that your child has a good play environment.
