Building blocks kids love

All reviews

Our three children are always coming up with new ideas and love to just throw themselves into their work at the end to destroy everything. Even our youngest (1.5 years) can build her first structures because the blocks are so light.

— Benjamin

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

— Family H.

We could throw out every other toy we own and my kids would still be happy because all they want to do is play with their RIWIs! It promotes imagination enormously—everything from caves to entire castles is possible.

— Lauren M.

By far the best investment for indoor play. These blocks are functional, well-made, and allow kids to tumble and climb safely without any hard edges. Finally, a solution that keeps them active and safe at the same time!

— Mary H.

Radiant children's eyes and huge building fun! The material is soft, light, and grippy—perfect for stacking. A highlight is letting a tower fall over together and landing softly in a mountain of blocks. Odorless and high quality!

— Philipp

Just purchased my second set. There are many companies out there—but buy the original. The quality, versatility, and the fact that it still looks great in our living room makes it worth every penny. Absolute recommendation!
