Product description
EASY TO BUILD WITH!
Build in 2D
Build in 3D
Build Geometric Shapes
Learning Comes With Play
They won’t know it at the time, but you’ll be smiling as you see them learn and develop while playing with Kadu. It might start with color-recognition and pattern-making, while at the same time building hand-eye coordination. Or, see the mental connections forming as a determined mind tries new ways of keeping their building from collapsing.
An Anywhere Toy
Kids are always on the go and always wanting something fun to do wherever they are. Just pop Kadu back in their reusable container and they are ready to go, too. Small and quiet, they are great for taking on the road, to restaurants, or to fill those “forever long” waiting room times.
Have a younger builder? KADU comes in two sizes!
