THIS IS THE LEGEND. It’s profoundly effective. Our customers have been trusting our Black Crystalline for years and it’s what has contributed to our success, including our blends, like Pink Bali Fibro blend/nerve blend. This is the stuff we’ve been out of for over a year. We’re finally back in stock! It sold more than anything in our store. I strongly urge everyone to try it. We’ve sold thousands of packages, but not one has EVER been returned. This speaks volume!
