What are Toobeez? Think of them like a life-size set of TinkerToys. Toobeez are an open-ended construction system that features a set of colorful tubes and spheres that can be connected to one another in a variety of ways. This allows anyone above the age of 4 to build life-size structures or create almost about anything that can be imagined. With 57 pieces inside of each box one can build many different types of structures, such as forts, castles, playhouses, mazes, obstacle courses, dollhouses, puppet theatres, soccer goals, airplanes, spaceships, or animals.
