The Ardesto AR2627BH set includes two double-wall borosilicate glass mugs, each with a 270ml capacity. This specialized glass material allows the mugs to withstand temperature changes from -20°C to +150°C, making them suitable for both microwave and dishwasher use. With a height of 10.5 cm and a top diameter of 8 cm, these glasses are designed for those who enjoy their beverages at the same temperature for longer. The double-wall construction creates a thermal barrier that keeps your coffee or tea warm while remaining cool to the touch on the outside.
