These were very poorly packaged to ship to me, just thrown into a plastic bag. One of them opened slightly and the oil leaked all over. Also, they arrived very hot from sitting in a mail truck all day in the sun. I'm sure the product is fine if you bought it from the store but I'm not sure if heating it will cause it to become rancid. I have kept it though because I can't get to the store to shop right now, recent surgery. Something is better than nothing. If it tastes bad when I open it I will try to return it when I can drive again.
