It's not just in the movies. People really do spill coffee all over important things. You don't want to find yourself in that position, and you won't with the Mighty Mug Biggie. Using patented Smartgrip technology, the Mighty Mug creates a powerful airlock when it's put down on a surface--and easily releases when you lift it. You've got to try it to believe it!
Smartgrip technology fastens against flat surfaces to resist spilling when you knock the mug
BPA-free plastic is environmentally friendly
Fits in any car cup holder so you won't have to worry about spilling in the car
Dishwasher safe: just throw it in with the rest of your dishes
