Double wall glass cup. Capacity 330ml set of 6.

Made of ultra-light, heat and condensation resistant, hand blown borosilicate glass.

Crafted by expert artisans, the double wall glass construction gives thermal properties to help keep your tea hot while keeping the cup cool to the touch. For cold drinks, eliminate the need for coasters as no messy, dripping condensation occurs.  Beverages remain hot or cold for extended period of time.  The glass also allows the shimmering colors of the tea to come through.
