This mug will put a smile on everyone's face and will surely become a great conversation starter!
Without liquids or at room temperature, the mug is black. As soon as you pour in a hot liquid inside it will start showing a beer pattern changing color until it looks like a beer jug.
Once the temperature starts decreasing, the mug will return to its original black color.
The color changing beer mug is a fun gift idea for a beer lover, an original housewarming gift, stocking filler or just enjoy it yourself!
