The clay is so incredibly hard we can't even begin to make it moldable with the warmth of our hands. It breaks and crumbles.

Easy to assemble. Comes with everything you need (except 2-aaa batteries) easy enough to replace, but letting everyone else know to buy extra lights in case they are as used and loved as his was.

Don't want to give this to grandson and give granddaughter the one on the right with twice as much stuff and much nicer. Only about 6 inches in height. They really need the dimensions on the description website.
