The Clever Up! Unit Wooden Block Building System 4.0 is the ultimate wooden building block set from HABA of Germany.
Strong enough to withstand rough and tumble play and large enough for small hands, these blocks will be a staple in your playroom from late infancy well through school-age. Your young children will begin by clutching and stacking a few blocks at a time and eventually master creating patterns, towers or even mosaics.
The magic of this set comes down to the unit cube. The 1¾ inch cube is halved and quartered into triangles and rectangles or elongated into strips and panels.
System 4.0 includes 160 blocks. All of the systems are compatible so additional sets can be added whenever your junior builder has mastered your original set and needs an additional challenge.
