This product is a tray set applied with the principle of magnetism. I have checked the mistakes occurred in carrying
foods of restaurant servers and attempted to think a way to complement the problems. When foods are carried, due to
the law of gravity, the magnetic under the tray and the magnetic under the bowl are connected and magnetism arises.
But, when the tray is put down, due to the spring inside the handle, a gap comes up upper side and bottom side, returns
to the original state, so magnetism does not arise any more and the bowl can be detached easily.
