This white ceramic mug is festooned with the Emacs logo, and like Emacs it's versatile: It will hold eleven fluid ounces of coffee, tea, cocoa, yerba mate, a toddy of any kind, mulled cider, boullion, sake, Postum, buttered rum, bandrek, anijsmelk, posset, pretty much whatever you pour in it, so long as it remains upright. Pens and pencils, too. An excellent gift for the Emacs-proficient beverage enjoyer. Inscription on reverse mirthfully implies that Emacs will refill your mug for you; please note that Emacs' beverage replenishment functionality is still undergoing preliminary testing.
This mug is also available as part of the All Things Emacs bundle.
