This Alias Two-tone Travel Mug has a dual identity. On the outside, it's a colorful and fun accessory, but on the inside, it's a stainless steel super hero designed to work hard for your beverages every day. The stylish and strong travel tumbler holds 20 oz. with the lid off and 18 oz. with the lid on. The outside is made of stainless steel in your choice of vibrant color; the outside is standard stainless steel with double-wall construction that will keep beverages hot or cold up to 6 hours. The outside color stops just before the top to give the tumbler a gray steel rim for a two-toned look. The snap-on, spill resistant lid with rubber gasket and the non-slip bottom help keep contents secure. Add your school name, inspirational message, or other one-color imprint on one side to create a custom travel tumbler especially for your school.
