Hi again. I don't personally care for their FO's. Which wax are you looking at? I know a couple specifics if you tell me which one you're interested in. It wasn't until I started buying by the cases, that I actually knew what brand of wax I was using. The IGI info was on the side of the case. Otherwise, they just repackage the slabs and flakes with their info. I'm not sure how much help I can be, but PM with the one you're looking at.
