Seller is trying to give me partial refund on this order and I barely even used this product I literally only used 8 CRYSTALS in counting which gives me only HALF A TEASPOON AMOUNT. THE BAG IS STILL LIKE NEW BARELY EVEN USED ONLY ONE TIME. IM VERY AWARR OF HOW TO USE THIS PRODUCT I REMEMBER WHEN THIS PRODUCT WAS CALLED BLUE STONE NOW IT'S CALLED COPPER THIS PRODUCT HAS BEEN OUT EVERY SINCE THE I WAS A YOUNGIN AND THE SELLER IS TRYING TO TELL ME HOW TO USE THIS PRODUCT. I'M VERY AWARE HOW TO ISE IT. I'M DISAPPOINTED AND GIVING 1 STAR RATING 😔 I CAN NOT BELEVE THIS IS HAPPENING RIGHT NOW.
