This is a set of four vintage Pyrex "Drinkups" mugs.  These mugs have a glass bowl with a removable plastic base and handle, making them suitable for hot or cold drinks.  The mugs are in a classic avocado green.  These items are new in their original box and have very likely never been used.  Due to their age there is some wear on the box as seen in the photos.  This is an uncommon item and would make a great addition for any Pyrex or vintage glassware collector.  Thanks for looking!
