Death Before Decaf is one of our most popular designs and this holiday season we decided to honor it by taking a step further and turning it into a mug! We had seen photos of our friends all over the world putting our Death Before Decaf Stickers on their own mugs, travel mugs etc., so this is now a more permanent, dishwasher-safe option for them. It is ceramic and holds 11 oz of coffee, tea, or even hot cocoa but certainly, positively, DOES NOT hold any decaf fluids.
