Like your mugs chunky and a little cheeky? This is your new fave. In a chunky design with loads of room for your hot beverage of choice, it features an ombre mermaid tale background, with shells and sparkly stars on each side, and holographic lettering which says 'I'm busy under the sea, so I can't hear your bullshit'. Whether you want to keep it facing outwards on your desk at work to get a message across (no judgment here!), or just to give you a chuckle at home, take this one home today.
