Zoob is the greatest snap, click and pop together toy! Pieces come in 5 slightly different shapes and 5 colors, and all interact with each other. Zoobs are intrinsically easy to use, so kids are not intimidated by complex connections. Simply push together and pull apart! And once together the pieces can move and rotate, increasing play value. Unlimited, open-ended building potential spurs the imagination but the 40 piece travel set does come with directions to create 22 amazing creations, as well as a clear vinyl carry case with shoulder strap. There is also a special piece that provides a stable base for building or standing your constructions. Perfect, success oriented construction toy will also improve hand and arm strength, motor planning and bilateral coordination!
