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.

Sometimes it's easier to find the answers to complex problems while you're in the saddle with the world flying by. Get fueled up for your next great ride, or keep 20 ounces of caffeinated bliss on your drafting table while you sketch your newest invention.
