This set of wine glasses are heavy and generously proportioned, which makes them a satisfying receptacle for wine coiffing. TANK is made from mouth-blown clear glass, defined by their simple shapes that were inspired by the rigour of science laboratory equipment. With crisply cut and polished edges and a sharply applied band of precious metallic copper detailing, these wine glasses provide the perfect functionality for modern drinking. Please Note: This is a handmade product, and therefore variations may occur. Colour change may also occur over time due to the character of the material. Care instructions: Hand wash only. Do not use abrasive agents as this will damage the surface.
