Endless opportunities and gets played with every day in our house.


Brilliant! Such good fun and so many building challenges! My 9yo girls love making things with them and we use them with the semis for making houses for our Nins with my 2yo.

Open ended and creative play

My daughter and son both love the Grimm's rainbow. They have already built so much with it already and we can't wait to add more great Grimm's to our collection! The rainbow has promoted a lot of creative play and they are learning so much about balance and physics!


I got the rainbow for my daughters second birthday. It was a big hit with the whole family with many of the adults playing and building with it after the kids went to bed.

Great quality open ended play toy

Gorgeous colours and lots of play options


Such a great toy for kids and adults alike. It’s so open ended and really gets them thinking. Will definitely be buying more in the sets!
