There’s nothing worse than brewing a glorious cuppa, only to nudge it by accident and spill your drink all over your laptop. That’s why Mighty Mug have designed a mug that’s nigh on impossible to knock over: its unique base grips the surface of your desk when pushed from the side, so you can sip without fear wherever you are. Available in three colours, each Mighty Mug is double-walled to keep your drinks hot, and made entirely from BPA-free plastic. Height: 16cm Diameter: 8cm Capacity: 320ml Care instructions: Dishwasher safe on the top shelf. Not microwave safe.
