Not to be confused with face masks (those white surgical ones people wear when they’re sick).
These are purely cosmetic treats.
Not just a treat for your skin but you can also trick-or-treat wearing these.
(I don’t actually recommend that)
Various themes, from traditional Japanese kabuki masks to popular characters can be found.
Above is the Nightmare Before Christmas, but also Marvel characters like Iron Man and Captain America are available.
You can find them in stores like LOFT or Tokyu Hands.
