Starbucks owns Teavana and is planning on another 1,000 stores in the U.S. alone. 

Description

This is a new take on classic diner mugs. Made of borosilicate glass, these double-walled glasses have a strength and durability above that of traditional glassware in spite of their delicate appearance. Light travels through the double wall, illuminating the tea liquor within for an enhanced appreciation of the tea. The double wall insulates so the exterior remains cool to the touch. The lovely frosted interior softens the appearance while modernizing the design. Holds 10oz (295mL) of tea. Dishwasher safe. Teavana Exclusive.
