Very durable, plenty of pieces to make something substantial. Easy to use good for little hands. Great for distracting the younger kids for a bit. Def recommend more than one pack and in other colors.

The kids love them. They're made sturdy. They're made really good amd they have a great teaching vaule also. It's something they can't get hurt with so even better. I have to buy every color now!

OMG, my grandson and his friend loved playing with these building chips! The chips were made out of plastic and easy to put together. I liked that it brought out their creative side. They were already asking if they could get more and if they could keep these!
