This set of 4 double-walled thermal mugs called Liss keeps your coffee or tea warm for longer. The stoneware mugs from House Doctor are coated with a dark gray glaze adorned with matching dots that have a slight shine when light hits the surface. The handleless mugs are easy to grip and hold thanks to their tapered design. Use the mugs when you have guests over, for a cozy cup of tea in the evening, or for a well-deserved break in the afternoon. Or whenever you feel like having a warm drink. The thermal mugs are the perfect choice for everyday occasions that can certainly have a touch of elegance.
