Sometimes we come across mugs that aren't quite up to the standards we expect of our products. Instead of filling up the landfill with things that are pretty good but not perfect, we're making them available at a steep discount. These mugs may have some blemishes in the ceramic or may have some slight printing errors.

On mornings when the magnetic pull of your coffee pot feels particularly strong and you just... can't... resist... another... cup, a 20 oz mega mug is sure to get your current flowing. Light up your day with electromagnetic brilliance and be inspired by Nikola Tesla's inventions and Maxwell's equations. This enormous mug will hold enough coffee to keep you going all throughout your physics lectures and well into your late-night study sessions.

Opt for a 20 oz mega mug on days when a regular cup of coffee just won't cut it.
