Very light and made of polystyrene, melted to shape then painted. not too bad though.

I ordered 100 grams of rocks, thinking it was a single piece. And a bag comes with several small stones, which do add up to 100 grams. I can't complain; I'll find a use for them too.

They worked for what I wanted them for.

I chose the largest diameter stones but they arrived in two completely different sizes. There were only two stones: one small and one large. Being real and heavy, they are very compact and difficult to make smaller and usable, so I couldn't use them for the purpose I needed them for.
