About the double-walled MELIOR tea glassThe MELIOR tea glass, the latest addition to Boden's iconic collection of double-walled glasses, is inspired by the elegance of Moroccan mint tea glasses, but has a modern twist. These double-walled glasses, individually hand-blown by craftsmen, consist of two layers of heat-resistant borosilicate glass, which ensures that hot and cold drinks maintain their ideal temperature for longer. A clever silicone valve at the base regulates the outer wall of the glass, avoiding greasy condensation and scalded fingers. These beautiful glasses, lightweight and comfortable to hold thanks to their unique shape, look like a work of art. The double-walled design creates the optical illusion that the glass contents float in the air. In any case, these tea glasses will add a touch of elegance to your tea ritual.
