JOEmo Is an elegant new design in coffee/ tea mugs that features an 1/8 stainless thermos mug which keeps coffee and tea hot longer than any other mug and is absolutely leak and drip proof with the final top on. The mug comfortably holds 12 ounces of your favorite brew (fair trade, of course!) • JOEmo can be carried in your briefcase or backpack. Sip JOEmo anywhere around its drink top. No need to find the drink hole while driving, it's anywhere. Have hot tea or coffee in the car, boat, bike or plane. Take the empty mug through security and fill it up before your flight. JOEmo® comes in its own travel bag. Push the center button to drink and touch the plate around the button to shut the top
