Amazing building tool!

These are a fabulous edition to our building blocks and rainbows. The kiddies have sooo much fun stacking towers and building walls with these rainbow boards. We also created some fantastic marble runs with them paired with the small stepped tower

An essential

These boards expanded the building possibilities of our rainbow and large stepped pyramid hugely. 3.5 year old loves them. An essential addition to the set.


Grimms Building Boards are fantastic. Wonderful addition to any build. My son uses them as roads for his cars, in his ball runs aswell as in structures he makes. Highly recommend!

The only store I buy Grimm’s from

I placed my order on Tuesday afternoon and received it the following day (from Adelaide to Melbourne), beautifully packaged with a handwritten note from the vendor. The items themselves are great quality and my daughter plays with them daily.

A must-have for our collection

I debated whether or not we needed these building boards as I wasn't sure if we would use them just with our rainbow - but they offer so many possibilities beyond what I first expected. They are the perfect platform for so many of our castles and buildings, perfect for stacking and perfect for lining up along the floor as a road. Can't fault them.

Useful addition to the Grimm's Rainbow

The boards have allowed our little ones (2, 5, 7) to expand their creative play with the rainbow pieces, turning them into bridges and roads for cars, ball runs, castles and rainbow runways. They are pricey but a valuable addition. Recommended.

Top quality product

Top quality and versatile product, goes well with LSP, rainbows and more.

Glad we got these

Wondered for a long time whether to get these but so glad we did. Have been used lots in our buildings already. Very handy.

Mehri Doyle
Useful for many purposes

Handy to go with semis and the large rainbow

Adrienne Holobowski
Great addition to the large rainbow

Purchased to put away for Christmas when my son will be 18m. The quality of Grimms is amazing, and I know these boards will have so many uses, especially to build up with the rainbow and make ball runs! Was going to get natural but thought it might be easier for younger kids to have the colour matching to know which size is right when building towers with the rainbow.
