Cheap and tacky packaging. One side of an envelop wrapped around and Salo taped to make kind of a bag. Couple of dates written on one of the bottles in Chinese both or past dates. With the help of a friend and I suspected; one is teh production date and the other is the expiry date. I understand the expiry date for these is not as critical as for food products, but the fact it has one it may indicate deviation from specifications such as larger particles being formed, faded colour, etc. I am returning it today.
