iHerb Customer Reviews
I specifically ordered ALUM CRYSTALS for an Art Project and was sent Alum Granules. This product was not what I ordered, as it is non-irradiated(a word that I did not understand, and in fine print on the package. I advised IHerb that the granules did not Crystalize as I had hoped, and sent back the unopened package. I am still searching for the ALUM CRYSYALS, and have not found them. I need this by September 9th, and need your help. Thank you, Jan Clark
