Kosta Boda Rondo Water Goblets Blown Glass Controlled Bubble 6 1/8" Tall Lot 2

Kosta Boda Rondo Water Goblets Blown Glass Controlled Bubble 6 1/8" Tall Lot 2 They measure 3.5" across the opening. They each have a single controlled bubble in their stem. From the 1970s. Very good condition. No chips or cracks. One stem has some ash that got into the glass at time of manufacturing which you can see in the last photo. It is deep inside the glass and should not be considered a flaw, just a natural part of the glassmaking process.
