After lots of emails & community feedback it was finally decided that these were fake, I refunded the buyer-
Be extremely careful on all the 'YOT' releases (re)packed by Imperial Tobacco with no serials & box codes. They are seemingly hard to fake b/c of the intricate bands, numbered box, etc. but apparently not. My guess is someone on the inside in Spain has access to real boxes/bands, and slipping some boxes into the stream. Lots of unknowns these days, lesson learned.
