This set of four thermos from House Doctor is double -walled, so your tea or coffee stays warm for a longer period of time. The Liss mug is produced in stoneware and completed with a gray glaze with smaller, conscious imperfections that create a rustic and relaxed expression. Instead of a handle, the mug has a tapered shape that makes it easy and comfortable to hold around it. Use it for afternoon coffee with your friends or a hot cup of tea in the evening. You can use the mug at any time. The set is a practical choice for situations that require a little everyday elegance.
