I will be quite frank. This was one of my go to fidget toys as a behavioral therapist. This little toy is simple,durable,and effective. I have had students throw them across the room and they are easy to put back together. This provides a simple puzzle that is easy to grasp and travel with. It also provides a tactile sensation as the child pushes the pieces in to place. This improves focus, helps with fine motor skills and analytical thinking. I still keep mine and can genuinely say this is one of the best investments you can make.
