Jess Medlock
Exceeded our expectations!

Wow! I am SO glad I purchased the medium natural tunnel for our collection! My 2yo son has had his Large Grimms Rainbow for about 7 months now and it has been played with so much, but I felt it was time to add some accessories to it. Unsure with what exactly to add due to the amazing selection available, I settled on a medium natural tunnel. As soon as I passed it to him, his face lit up and he said ‘a new rainbow, thanks mum, i love it!’ It’s the perfect size for little hands, and while it’s only 6 pieces, he’s been playing with it just as much as the large rainbow. They work so well together with wooden train sets, 7 friends in bowls, our ostheimer animals, and so many other toys. It goes to show that even the most basic of toys are a world of excitement to children.
