Kids Stepping Stone Kit is very nice product. Love these rocks. My kids love playing with them in many ways (my 2yr old calls them “pizza” thanks to his big brother).
The only thing I don’t like is that they don’t have any grippers on the bottoms so they do slip a little bit on carpet (and are NOT great for smooth floors because of that). They hold up well to being chucked all over the house for all things non-stepping stone though.
Attacking some grippers to the bottoms will likely help with the one issue.
