Cool Blue Happy Stacks
Our Silicone Happy Stacks are the new must-have montessori toy. Classic stacking cups just got a massive upgrade. This set of 7 square silicone stackers teaches stacking, nesting, counting and sorting to develop concentration, problem-solving and gross motor skills. They're great to have around the house, for everything from playtime to mealtime and even bathtime. And they nest together, which makes them perfect for on-the-go. Sounds like it's the only toy you need, right? We know!
