Funny Middle Finger Color Changing Coffee Mug - Heat Activated Novelty Gag Gift

Say exactly how you feel without speaking a word.

The Funny Middle Finger Color Changing Mug is the ultimate mood-transformer for your morning routine. At first glance, it looks like a sleek, ordinary black ceramic coffee cup. But once you pour in your hot morning coffee, tea, or cocoa, the high-quality thermochromic coating reacts to the temperature shift. The solid black exterior quickly fades away to reveal a bold, hilarious middle finger graphic.

It is the perfect passive-aggressive desk accessory to warn coworkers before you have had your morning caffeine.
