This set of four thermos from House Doctor has a hollow design so your tea or coffee stays warm for a longer period of time. The Liss mug is produced in stoneware and complete with a dark gray glaze with tone-in-tone dots, which add a touch of shine when the light hits the surface. Instead of a handle, the mug has a tapered shape that makes it easy and comfortable to hold around it. Use it for guests, for your evening or a well -deserved break in the afternoon. You can use the mug at any time. The set is a practical choice for situations that require a little everyday elegance.
