With Dado Bricks - imagination is spectacular. It's quite a rush for a little kid to see that he or she is capable of building something so big! That's just the first stage of the fun with giant cardboard blocks. Then, out of the stacks of huge blocks comes imagination. Once a child connects that they can make walls and corners - they don't need any prompting. They start building grocery stores, airplanes, stadiums... there's no stopping them! Dado Bricks offer all that fun - plus, the interlocking nature ensures that when Dado Bricks are stacked they won't easily tumble and retain a rigid structure. Building opportunities escalate! At long last, kids can use stacking bricks to create structures that last beyond three minutes!
