The cornerstones were an addition to our collection for making marble runs. They have so many more uses than that, though! My kids put four together to make 'tents', stack them as high as they can for pretty towers, use their brains to figure out how to put them together in the box properly, use them in buildings they make with their toys, use them as decorations in small worlds etc. They're light and have an amazing feel, inviting children to come and play with them!

These cornerstone blocks help take building and ball runs tot he next level. The colours are complementary to both the pastel and bright Grimm's colours. When I first received them I thought they seemed small. But in the right place the size makes sense. The box to contain them all is also really useful. Everything you'd expect :)

We bought the cornerstones to go with our large stepped pyramid... they pair beautifully and they are everything you’d expect from Grimms 💚💙❤️💛
