Bought a small jar for around $15.00, used just a little bit of content making sure that I follow the instructions. Air tight was the major concern and I make sure I was doing it right. Couple of weeks later I went to used it again and it was hard more than 75%of the product. Very disappointed cause I paid a lot of money for maybe used 1/2 an ounce and have to throw the rest away. Well it is what it is.
