Tweetthe ridges on the bottom mean nothing. Ok look at the halo again reall good. Only the older halo's leave circles. The newer ones have slits in the halo's. Looks like someone too a razor blade and cut an x in it. Their little slices. If you messed up the halo pealing it off you can look at the glue left behind on the bottle and you should see lines in it. If your still doubtfull post a pic so we can help you better.
