20oz, here for the Multiple Drinks Crew!! (That's what we call ourselves; we love having our water, caffeine, electrolytes... all the things throughout the day.)
This cup is double walled and vacuum sealed. It's diswasher safe. The lid should be washed by hand for longevity's sake, but will be fine if you throw it in the dishwasher. Lid is made of plastic. Magnet lid is convenient for keeping temp, but it is NOT spillproof, FYI. Please don't be tipping your drink upside down... this tumbler will spill if flipped over. All tumblers final sale.
I love this tumbler, and would definitely get it again!
