Great rocks for more or less any setting. Depending how you paint them or what foliage you may or may not attach to them, they're great for deserts, jungles, rocky hills, alien planets, could even be painted with encrustations of ice and snow for tundra settings.
A decent size at the "Large" option, those with flat upper areas making very good high ground for creatures to stand on.
As with all the stuff (quite a lot of it) that I've had from QP3D, these rocks are sturdily made and require almost no clean-up before priming and painting. (I primarily use Mig Ammo Atom and Vallejo paints, but any decent acrylics will serve fine).
