Portable Thermal Stainless Steel Mini Coffee Mug

The cup is easy to carry and can be put in your backpack or bag. There is a silicone handle above the bottle cap and you can carry it by hand. If you go indoors, you can hang it on the wall. There is a waterproof silicone strip inside the lid, so there is no need to worry about water leakage. The water inside the cup is still not dripping when you shake it arbitrarily.
