This set would be good for learning development if it hadn't come with millions of splinters. There were large shards sticking into the holes, to the point that not only was it super dangerous for kids, but also the marble wouldn't even fall through. My husband and I spent 45 min sanding every face of every block. After we did this, it's a pretty good set. The design is pretty good, they just have a MAJOR quality control issue from their factory.
