HONG KONG — Assume, for the sake of argument, that KFC’s fried chicken is, as advertised, “finger lickin’ good.”

Would you really want it to remain on your fingers? Indefinitely?

These are just two of the salient questions raised by the chicken chain’s new Hong Kong marketing campaign, in which it is offering lickable, edible fingernail polish in two flavors: Original, and Hot and Spicy.

“Yes, it is actually a real thing,” said Anna Mugglestone, marketing and communications director for Ogilvy & Mather Group in Hong Kong, the agency running the campaign. “I tried it myself in the office when they were doing testing.”
