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.


  • SIZE : Each cube measures 1¾ x 1¾ x 1¾ inches
  • MATERIALS : Hardwood from sustainably managed forests
  • INCLUDES : 160 pieces: 18 panels, 30 strips in four lengths, 4 ball bars, 6 balls, 36 cubes, 24 rectangular blocks, 30 rods, 12 triangular prisms; heavy-duty cotton storage and carrying bag; educational booklet
  • CARE : Use a cloth dampened with warm water. You may use a small amount of vinegar essence mix combined with water. This works extremely well in destroying bacteria and cleaning wooden toys. Please Note: Do not submerse in water or place in dishwasher. Disinfectants (even organic baby wipes) should not be used as they can damage the water based coatings that protect the colorful stains beneath.
  • ORIGIN : Germany

Wood is a natural material and as such, has various unique markings. Variations in wood grain, color, knots, texture or dye transfer are all natural occurrences in these hand-stained wooden products. These unique variations and markings are proof of quality, not defects. Enjoy the markings that make your wooden toys unique!
