The vibrant vintage pair are comprised of curved copper bowl discs with nicely textured foil enameling -- which have a glistening mosaic of red, turquoise, blue, green, and black abstract shapes over a white ground -- for an almost stained glass look.
The backs are also nicely enameled -- and they measure 7/8 of an inch round, are screwbacks and have a total weight of 9.1 grams.
