Everyone should already know not to bother you when you're having that first cup of coffee in the morning. But just in case, you can give them fair warning of who they're messing with by choosing this cleverly designed mug. Inspired by Fantastic Beasts and Where to Find Them, the mug features a MACUSA wanted poster attesting that you're "Wanded & Extremely Dangerous." Let's just hope you never have to prove it. This white ceramic mug holds 20 ounces of your favorite hot or cold beverage and is microwave and dishwasher safe.
