GOMUG, a stainless steel mug that can fit a coffee cup from a convenience store or coffee shop, has a two-layer vacuum insulation structure that keeps the temperature firmly, so you can enjoy it until the end. If you put the cup in completely, it will prevent condensation, so you don't have to worry about staining the table with water droplets or getting your hands wet. It can also be used as a thermal mug to pour directly into coffee, tea, or other beverages. It's convenient to keep in your car! If you put coffee you buy at a convenience store or parking area, it will keep the temperature well. *Depending on the size of the drink holder, it may not fit. The surface is sandblasted to resist scratches, so it can be used outdoors with confidence. The bottom is made less noticeable by eliminating paint, making it less noticeable and can be used for a long time.
