When the traditional tray is carrying the drinks, its always heavy and unstable.
Handy Tray is designed to solve this problem, it has three holes on the plane, so the holes can fit in the drinks, salad, soup ...etc . The holes are in the middle, closed to the center of gravity, so it’s more stable than the traditional one to carry.
