Clever Mug Design
Have you ever noticed these strange little holes on the bottom of a cup or mug? Those things aren’t strictly for looks! They are useful in preventing water from pooling on top of the mug during washing.
It also prevents mugs from sticking to coasters or tables when they’re wet, adding another layer of protection. It puts in a lot of effort for such a basic design. Simple designs can be quite helpful in daily life.
