Must Have for Rainbow Fans

If you have the Rainbow, you must get this as well as it really expands how bub (and, let’s be honest, yourself) plays and builds with the Rainbow. ;)

Great Start to Do the Vehicle Play

My son loves to use them as roads and train tracks; and use the rainbow to be the tunnels. It’s a great start for him to do another level of play.

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 with the rainbow

From the moment we opened our beautiful package from OWA we knew we were on to a winner. The boards have really expanded the way we play with the rainbow.


We bought these together with our large rainbow and have been having so much fun with them! Our favourite thing at the moment is making ball runs and roads for cars. Has enhanced our play with the rainbow and I’m glad I bought them.

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.

Simple is best

These building boards are one of our most used toys, so many ways to play with them.
