Here’s a fun way to start your day with your morning cup of coffee, the on/off coffee mug.

This fun mug is black when there is no coffee in it or when you put a cold drink in it, and it displays the word ‘OFF’ on the front.

Add a hot drink like tea or coffee and watch it change colour from black to white, and the text changes from off to on.

The On/Off coffee mug is available to buy online for $28.78 from IWOOT
