Bests & Worsts Reviews from Amazon

The ingredients are not visible anywhere prior to buying, so let me tell you what I discovered. Upon opening the box, there are 25 packets inside. The instructions say, PLACE UNOPENED PACKAGES ON ANY INDOOR/OUTDOOR WOOD BURNING FIRE - DO NOT COOK OVER COLORED FLAMES. That's the first warning - it's unsafe to touch the powder inside, and secondly, you'll be burning a heavy plastic packet. I'm an engineer, but you dont have to be one to know that fumes from heavy plastic wrappers are toxic and should not be inhaled. Next, and far more significant, are the product ingredients themselves: Cupric Sulfate, Cupric Chloride & Polyvinyl Chloride While one packet did provide fantastic blue green colors for a decently long time, these chemicals, especially when burned, are unsafe for humans to breath their fumes. THIS IS A TOXIC PRODUCT! BEWARE!
