Discover HABA's Clever Up! Building System, the ultimate haven for wooden block enthusiasts!

Let your kiddos get lost in the world of wooden building blocks, constructing bridges, inclines, and innovative designs. Not only do they keep tiny hands engaged, but they're also a fantastic tech-free alternative to boost cognitive growth.

With the Clever-Up! 2.0 set, enjoy 66 pieces including cubes, baseplates, slats, and more, plus an educational booklet all stored in a chic cotton bag.

Size does matter - our cube measures 1 ¾“ x 1 ¾“ x 1 ¾“!

Want to keep those wooden blocks looking pristine? Just wipe 'em down with a warm cloth and a splash of water-vinegar mix. Voilà, bacteria be gone! Remember, no soaking or harsh cleaners. Just a little love goes a long way.

And hey, perfect for tots aged 1 and up!

Kick off their block party with Clever Up! 1.0 and watch them graduate to the epic Clever Up! 4.0 (we're talking spheres and balancing acts, folks). Oh, and did we mention each set comes with a snazzy storage bag and a splashy guide to help you secretly infuse some math, geometry, and - dare we say it - physics fun? 

🧸 Ready to offer your child endless hours of imaginative play while you sip that coffee uninterrupted? Dive in!
