High quality, good size, but arrived wet
The actual product was very good: consistent grain size and no dust. However, it was sold by weight and the lava rocks were wet when they arrived and the resulting bag was smaller than expected. I hope that the wet rocks were due to them washing it the dust off, but water definitely adds to the weight for a product like this that is sold by the weight.
