Spend your coffee break with the Norse thunder god! This Mighty Thor Mug would be great for holding hot drinks. The mug is made out of super-thick ceramic and has a nice large Mjolnir Hammer handle for easy grasping. It's stylish, too! With a classic picture from Marvel's Mighty Thor comic books of the Mighty Thor in a battle pose, this 15-ounce mug has a cool black design. This item is not dishwasher and microwave safe.
