This is a set of 8 - 16 oz. Cooler glasses made by Libbey Glass Co. in the 1980's in Ohio.  The pattern is named Concert Pink and is described as Swirl Optic Pink (Dusty Rose).  They have a slight hour glass shape and feature a nice heavy bottom for stability.  They are 6.5" high and 3" diameter opening and 2 7/8" base.  There are two sets of 8 each available.  The 2nd set sold will contain the cooler with the little black stone imbedded in the glass on the outside as shown in the last two photos. This is a manufacturing defect that must have missed inspection.  There are no chips, cracks or other flaws other than normal usage marks which are few. A set of 5 matching Old Fashioned Glasses are listed separately.
