vintage Japan stackable ceramic mugs, Christmas angel, Santa, red & green holly

Lot of two cute little ceramic coffee cups made in Japan - I've never seen stackables in a Christmas pattern before! Each of these is different, though they're the same shape and size. These measure 3 1/4" tall.

The mug with the angel and Santa Claus has a tight hairline to the handle (nearly invisible). They're clean and bright without scratching or wear.
