Black is slimming, it matches everything, it dominates your closet, and matches your soul and coffee. This mug is so cute, everyone at work will as where you got it. This design is a vinyl decal, don't worry it won't just come off with regular use. The vinyl I use is outdoor sign quality and will hold up. Please just make sure not to scrub the decal itself with a rough sponge. For longest and best wear be sure to wash by hand.
