The most comfortable lid opening and locking - open and close the lid completely with one hand! The RevoMax One Click Open Tumblers Carry-On Mug has a lid designed with buttons that you can press down to open or close it. It also has a ring that you can hook your index finger on to in order to use our water bottle with one hand.
With an air vent for pressure release - This also highlights the built-in air vent, which releases pressure before opening the lid. This is especially beneficial and useful when your takeaway drink bottle is filled with carbonated beverages.
Long-lasting temperature retention - Our flask's double insulation keeps cold drinks cold for up to 36 hours. On the other hand, it can keep hot beverages hot for up to 24 hours.
Super Safety Lock - The RevoMax One Click Open Tumblers has a double seal with a preset even and constant pressure applied to it, so nothing will leak. There's also its safety lock indicator, making it completely leak-free. It will never come loose and open accidentally!
Non-slip and easy to grip - The exterior of our flask has a matte finish and powder coating. It is non-slip and its copper plating maintains the attractive color. Better yet, this go-anywhere mug won't sweat!
