This is a set of 2 Corning USA White Milk Glass Cups, one with Wide Pink Band & one with a Wide Gray Band.  They are marked Corning Made in USA with the Corning logo on the bottoms, they are like Pyrex Glass. They are in very good used condition, no chips or cracks, they are shiny inside and out and the bands are bright and intact.  There are a couple of very tiny rough specks on the rim of the gray cup and the bottom of the pink cup.  They look hardly if ever used.
