These blocks are exquisite!! Possibly the most beautiful toy I’ve ever seen. They look like galactic space stations with gorgeous coloring light. Heavy, and durable, (not a multitude of small pieces). Wondered if I over did it by buying two sets, but the design possibilities are so exciting it’s worth it! Truly one of a kind heirloom blocks to last many generations. And they are so unique I love that we have something special.
