Definitely for solid chocolate and boxes but things like Mars and Snickers (or should that be Marathon?) are still portrayed as "manly" confectionery. It obviously works as I can categorically state that I have never been given a box of chocolates as a gift whereas my wife gets one about every two weeks on average.
As Yorkies have "not for girls" on the wrappers I'd say they are aimed at men, (unless it's reverse pschology) but mostly it seems to be aimed at women. Although if you believe the adverts only thin model types eat chocolate, but very slowly.
