These double walled glass cups are the perfect way to enjoy sip on a fresh cup of tea. The inner wall keeps the tea hot and suspends the liquor to highlight the cup's interior curve. The outer wall protects the exterior surface from heating so one can handle the cup without being burned.
All of our glassware is made with borosilicate glass, which is made to withstand rapid temperature change from –68F to + 300F. Designed in Berkeley, California, this cup should be hand washed.
