I finally got my package from QSC. Of course they are MIA right now. 3 of the 6 do not have any stamp on them. I got one of the stamps from a now deleted message with the codes definitions on them. All came in nearly identical packaging other than outside color. Not feeling super warm and fuzzy about having 6 packages with little to no identifying markings on them. Hopefully I don't grow man boobs. Any help is much appreciated. DM me if needed.
