The perfect travel mug for morning coffee, afternoon coffee, and evening coffee. If you're not a coffee drinker, use it for your afternoon smoothie, tea, or water! This 12 oz tumbler has triple-walled vacuum insulation, an insulated flip cap, and natural bamboo for a timeless look and comfortable grip. One of the best parts about it is that it's one of the best leak proof tumblers we have come across!
