Made from 100% BPA-free silicone, the Lytl Ring Stacking Toy safe, durable, and multifunctional. Your child can stack it, sort it, squish it, bounce it, and even use it as a pretend microphone (the more creative the better!). As your littles learn how to stack the pieces differently, they'll develop their spatial awareness, hand-eye coordination, cognitive skills, and creativity. Why settle for a mindless overstimulating toy, when you can have the Rustic Ring Stacker– a Montessori toy that’s safe, multifunctional, problem-solving, and creativity-boosting ALL IN ONE!
