Thermal mug is a bottle which is made of ceramics or stainless steel with hollow walls. The narrow region between the inner and outer wall is evacuated of air. Using vacuum as insulator avoids heat transfer by conduction or convection. Thermal insulation can keep an enclosed area like a warm building, or it can keep the inside of the container cold. If you would like to drink ice water, you can put the water into refrigerator, and then put the cooling water into the mug. The water will stay cold, because the ice in the water is not easily to melt. While using this thermal mug, you're supposed to avoid collision, which would result in insulation failure or water leaks.

You can also print with your corporate logo or specified designs on the mug according to customers needs. Thermal mug is always the perfect selection among the corporate premiums.
