I have a high functioning kiddo on the spectrum who loves the patterns he can create using these colored, translucent cubes. The boy is 11 years old and apart from kinetic sand and drawing highways and road scenes, he really likes this well made set of cubes. It's great eye candy and helps him regulate.

I purchased this item and was pleasantly surprised by how bright the colors are and how big the cubes are. The wood tray that comes with it is perfect at not only keeping everything neat and organized but also can be used as a place to stack the cubes! Side note, they are also pretty sturdy and comes in a pack of 100. Very happy with my purchase!
