The cubes are just as beautiful as the original. I love that they are beveled the slightest bit on the edges, so that they are comfortable to play with. I bought them for my grandson and I to enjoy together and he loves them, he’s 2 1/2 so we will enjoy them for many years!! Thank you CMY

Plato’s cubes

My grandchildren loved playing with them. They would stack them up and see all the colors on the tray. I like the feel of them.

Awesome idea for the kids

Plato's Cubes was an absolute hit when the kids came to visit for lunch. We had so much fun watching them rip off the wrapping paper and exploring the colourful cube pieces. It was great to see how their faces lit up as they figured out how the colours mixed together, and it was truly rewarding to watch them take turns understanding primary colours and colour combinations! All in all, Plato's Cubes provided a fantastic way for us to interact and bond with our grandkids during our time together!
