The answer to "I Love You" at my house is always I LOVE YOU MORE. If you do the same, this is a great way to send a reminder with the people you treasure when they are on the road or going to college. This double walled porcelain travel mug was created using all lead free, non toxic materials in my New Jersey studio. It has been kiln fired to over 2000 degrees and is safe to place in your dishwasher or microwave- made to be used and enjoyed for a lifetime. Top is hard plastic with gasket and has an open and close feature. Sturdy high fired porcelain will not chip easily and design will not fade with time. Measures 3.5 x 6 and holds 16 oz.
