A Japanese burger chain has come up with a new way to help women eat big burgers, keeping in mind the social etiquette in Japan that requires women to never open their mouth wide in public.
According to now.msn.com, the 'Liberation Wrapper' is printed with the image of a modest, closed-lip smile and it covers a woman's mouth while she attempts to eat the chain's Classic Burger.
The popular wrapper has reportedly increased the sales of the burger by 200 percent.
