This reminds me of a mail order scam perpetrated in the late sixties. The product was advertised as a breast enhancement product and it only cost 1 dollar (shipping was extra).
What the ladies received after sending in their money and waiting six weeks was an 8X10 black and white photo of a man's hand.
I'm sure that the photo worked just as well as the creams, stretchers, rollers, and whatever they sell these days.
