Mornings at work suck, so it's the little things that make it better, like a hot mug of coffee, and your favorite rap music (From the 90's). Mugs are 16oz double wall, BPA free. 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 is considered a permanent application. Not sure about vinyl products? Shoot me a message I'd love to yell you why it's the best.
