I've been a bit covered over the past 3 or 4 days, so I'm somewhat tardy where my follow up review of this vendor's products is concerned. However, having had a chance to sample them, I can attest to the legitimacy of his PK product offerings, at least those which I ordered as part of my trial order, which bore the imprints 3601, 3604 and 853 respectively. For those who prefer these products, those imprints should be at least somewhat familiar, or if not, rather easy to research. In any event, the products were again authentic, as well as fresh. End to end, my experience with this vendor was excellent in terms of product quality, communication and turn around time. Certainly a satisfying overall experience.
