This stuff when it is in plastic bottle it melts the inside of the plastic bottle and the bottle itself cracked. Then what we saw shocked us the melted pieces of plastic was mixed up in the liquid YIKES ...we bought another two bottle that were plastic and I noticed one bottle is looking like it is going to crack. Come on people what the heck is wrong with the manufacturer like Miracle-Mineral-Supplement has to be put in glass bottles just for basic human safety like who wants to be drinking plastic!
