Up for sale are a pair of 1-ounce jars of Perricone MD Cold Plasma Plus advanced serum concentrate.  Since I am not the original owner, I'm not certain of their exact age, but I've included a photo of the production batch code that's printed on the boxes (I don't see any sort of expiration date).  There is light cosmetic wear to the packaging from previous handling, but no major flaws.  Please be sure to fully enlarge the provided photos, and feel free to contact me with any questions you may have.
