Heat Changing Fuel Gauge Mug
It may not be as satisfying as filling up your car with fuel, but it almost comes close. As you pour a hot drink, the fuel gauge on the front of the mug starts to fill to reach the level of the liquid within - ensuring you know exactly how much coffee you have before it's time to get another one brewing ☕.
- Sturdy porcelain construction
- Double sided fuel gauge
- Trying to fill with fuel is not advised (duh!)
- Hand wash only
