The design of the usual things. Tea Bags and Saucer

“Where to put this bag?” - each time the same question arises. If left in a cup, you get a bitter and strong tea; if you put it on a saucer, the resulting liquid on a white saucer will not look aesthetically pleasing. If you take out of the mug and attributed to the trash, you can drip on the floor, table or clothes. With their decisions, designers strive not only to ensure your comfort, but even to save during a crisis.
