Building blocks kids love

All reviews

Our three children keep coming up with new ideas and love throwing themselves into their creation at the end just to knock everything down again. Even our youngest (1.5 years old) can already build her first creations, as the blocks are so light and easy to handle.

Great building blocks! What I especially love: they are washable. If you lay them flat to dry, they perfectly regain their original shape. We have the 48-piece set and build huge caves where several children can fit at the same time.

We could throw away every other toy and my kids would still be happy because they only want to play with their RIWIs! It boosts imagination enormously – from caves to entire castles, anything is possible. You won’t regret this purchase.

By far the best investment for indoor play. The blocks are functional, beautifully made, and allow children to romp, climb, and do somersaults safely – completely without hard edges. Finally a solution that keeps them active!

— Mary H.

Beaming children’s eyes and huge building fun! The material is soft, light, and easy to grip – perfect for stacking. One highlight is knocking over a tower together and landing softly in a pile of building blocks. Odourless and absolutely high-quality!

Just bought my second set. There are many providers out there – but buy the original. The quality, versatility, and the fact that it still looks great in the living room make it worth every cent. Absolute recommendation!
