Enjoy your morning beverage without wondering whether it's hot or cold with a Set of 2 Fill 'em Up Mugs. On each heat-sensitive 12-oz. mug, there's a "fuel gauge" much like that on your car. As hot coffee, tea or cocoa is poured into the mug, the gauge turns red. It loses color as it cools down to let you know when it's time to warm it up again. Porcelain with a glazed finish. Microwave safe.
- Pour in a hot beverage, and watch the gauge turn red!
