This is the perfect invention for those who love getting messy with a burger but also don't want anyone to witness the disaster. The napkin apparently liberates Japanese women who don't want to seem bad-mannered when getting down and dirty with their food. It's big enough to hide their entire face, and the company that invented this napkin became highly successful and had a great demand for their unique product.
In Japan, it's customary for women to cover their mouths in public, so a popular food chain restaurant was having trouble getting female customers to eat burgers. In response, they invented the "Liberation Napkin."
