Sometimes we come across mugs that aren't quite up to our standards. Rather than fill up the landfill with things that are pretty good but not perfect, we're making them available to our earth-conscious customers who love deals! These mugs have minor misprinting or minor flaws in construction.

Get fueled up for an afternoon of calculations and designs with a full 20 ounces of your favorite brew. With a mug this size, you can let yourself get lost in the finer details of soaring arches and spiral stairways without having to get up to refill.
