these are 4 corning/pyrex mugs.
3 say corning one says pyrex, but all 4 are the same.
they are blue outside and white inside.
lightly used, still look great.
they hold 8 ounces each, standard coffee mug size.
they are 3 1/2 inches high and 3 1/4 inch across the opening.
not sure which corelle patterns they match.
