If you feel uncomfortable with the product you may send t back for a replacement.
However I have seen this before, basically when the outer lid seal is being applied heat is used and it most likely was a little hot and burned the inner seal.
IT will be just fine, however you can check to see, is the inner seal inside the cap? Sometimes it comes off with the cap..Hey Prince. I am a new member and just received a Super DMZ 3.0 bottle with the inside seal missing. There was a plastic seal on the outside but nothing inside. I am guessing it is ok however I just wanted to see if you know anything about that one..... Thanks!
