Mug for those who are too fond of coffee

You love coffee, afraid to spill even a drop? Or coffee constantly dripping down, forming on the desktop and unpleasant stains marks? Coffee can sometimes be a real pain in the ass, no? But smart people came up with a great mug of The Drop Rest, which selects the small droplets, which fall down. Now no need to swear and wipe the droplets that fell on a hard surface. They all quietly congregate in a special slit.
