Earth's Geology 500 mL Steel Bottle

very cute

i fell in love with the beautiful and clever design! was afraid it wouldn't last warm bcs the bottle (especially the top) would get very warm after pouring the hot drink in. but surprisingly it lasted the whole night until morning for my breakfast tea. i appreciate the stainless steel on the inside of the top (my deal breaker). the only disappointment was a hard-edge transition of the design – visible in the picture i attached.
