A fast food restaurant chain discovered that Japanese women don't like to eat big burgers because they are ashamed of opening their mouths wide. So they invented this clever paper holder to hide their mouths while stuffing their face like piggy men. Surprisingly, the invention was a huge success.

The company claims that consumption of big burgers among female clients jumped 213 percent when it was introduced. Don't be ashamed, women of Japan, with or without mask, women or men, the only way to eat a burger is with a wide open mouth and juice running down your face.
