Set of 2 Starbucks Green Hand Blown Recycled Glass Tumblers- Rare & Hard to Find

TWO Starbucks EXTREMELY RARE Hand Blown Recycled Green Glass Tumblers- such a work of art! These beauties are nearly impossible to find. Starbucks mugs/glasses are highly collectible & can often be hundreds of dollars. Finding a PAIR is extremely unusual. I’m not an expert but I do believe that these are TREASURE. On the bottom of the glass, the “scar” is called a pontil mark, is an indicator of blown glass. Writing was pressed into the glass & says “DO NOT MICROWAVE” “FOR COLD BEVERAGES ONLY”.
