Finest quality glass cup that we recommend using when making Flora Tea™ (Flowering Tea™).

Please Note: You will find a small air-hole (blown hole) on the bottom of this double wall glass product, this is not a flaw but a safety means to control air pressure between walls. Normal circumstances, no dish washer, simply rinse with hot water. Clean the bottom gently, avoid brush, otherwise, there might be some water trapped inside the hole and fog up between the two walls. Mouth blown glass, each piece hard to make to perfection.
