Got this for my 7yr old son, when he opened it he played with it for an hour. He now plays with it before bed every night. It’s a great fidget product. Even the adults wanted their own box. I think one box is good for play but two would be great. Definitely buying more!The color of these are so pretty and they are so smooth. The magnetic part isn’t very strong but you can make play rings and small molds with it. But I bought this for use as a fidget toy rather than building. It comes in a nice metal box so the pieces don’t fall out making it easy to store.
