Health is an issue we concern. There is an unsanitary phenomenon that when we carry the bowl, our finger easily get into the soup. And when we turn the bowl upside down, all the edge touch the desk which is unsanitary.Whlie,it is hard to take it up.
"ARC DEGREE" just changes the bowl edge into arc edge so that it avoides finger into the food to make our life heathier.What is more,"Radian" makes the touch to desk less and solves the problem to take up.
