This is without a doubt the coffee mug for the office's weapon fanatic! The well-built and solid Brass Knuckles Coffee Mug is as badass as the name implies. You can both drink your coffee from the ceramic mug, and punch hostiles with the mug's metallic knuckleduster handle! Now that's the type of coffee mug every office should have with these days hostile corporate takeovers!
But it's also the perfect novelty item to bring some humor around the coffee table.
