Review on Olgachalkshop Red Nakumatt by Nicole Mcleod

I have bought this fodder several times and have been very satisfied so far. This last purchase was not up to par. You expect these pieces to be hard - that's the whole point - but this bag contained real STONES, not clay. I nearly chipped a tooth before realizing it wasn't clay but an inedible rock. This has put me off ordering from this seller again. I don't know about their source so I don't know who got it wrong but the quality control definitely needs to be better so you know what you're getting.
