Review on ☕ Costablue 16 oz. Stainless Steel Thermal Travel Mug: Vacuum Insulated, Easy to Clean, Leak Proof Lid, Silver Shadow by Evelyn Cacsire

Advantages:. I tested the costablue travel mug as soon as I received it. I poured boiling water in, closed the lid and set the timer for an hour. An hour later, as I emptied the cup, I checked the temperature of the water, it was still very, very hot. Good work! Disadvantages:. The inside of the lid has grooves to fit the drinking hole and an additional ear hole to release the liquid. While the lip that goes in the drinking hole is fine, the lip that goes in the air hole will poke your nose while you drink it. You could work on that with costablue and correct the design. In general:. I like it, it's purple, it keeps the coffee hot for a long time. Thanks very much!
