A South Korean company has released a new mask designed to help people feel more comfortable dining indoors by covering just their nose while they are eating or drinking. Behold: the “kosk”, writes The Washington Post.

The mask has gone viral on social media and in various online forums, after it was recently unveiled by a South Korean company, Atman. It can be used folded up when eating just to cover the nose, and unfolded to cover both the nose and mouth after eating. It is available on an online shopping website for about $8 for a box of 10.

The new mask is called kosk, or a nose mask — a portmanteau of “mask” and “ko,” the Korean word for nose. Kosk is typically used to describe people who wear their masks over their mouth, with their nose revealed.

Another popular invention is the “tuksk,” a combination of “mask” and “tuk,” the Korean word for chin. It describes people who wear their masks on their chin, with their nose and mouth revealed.
