Here at Happy Baton, we believe in renting over buying in order to leave the world a better place for our children. But some toys are meant to grow with your child and eventually become sentimental treasures that you'll hold dear to your heart. The classic Montessori puzzle ball and rainbow ball are designed for tiny hands to easily grasp, roll, shake, and eventually practice hand-to-hand transfer. The puzzle ball can even be hung up onto the play gym to encourage batting or kicking. Your baby will love it for years to come.
