VAVA 30 oz. Vacuum Tumbler | $11 | Amazon | Promo code KINJAHP3

Those stainless steel tumblers are all basically the same—they’ll all keep your drinks hot or cold for absurd amounts of time—but this one from VAVA is a little more...rounded (?) than most. It almost looks like a water balloon that someone squeezed at the bottom. Anyway, get it for $11 with promo code KINJAHP3, and gulp down the ice cold savings.
