Insulated Coffee Mug 304 Stainless Steel Tumbler Water Thermos Vacuum Flask Mini Water Bottle Portable Travel Mug Thermal Cup
The cup is easy to carry and can be put in your backpack or bag. There is an 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.
