Compare with common shallow round sushi tray ,here is some advantage of it
The deep bottom can effectively hold more liquid and avoid food leaks during transportation or handling, especially for some foods containing sauces, soups or oils.
The deep bottom design increases the volume of the plate and can hold more food, especially for layering or high food volume occasions.
The design of the deep bottom makes the food not easy to be crushed or destroyed, especially suitable for some fragile food (such as sushi, pastry, etc.).
Since the bottom of the plate is deep, multiple plates can be stacked to save storage space, especially in takeout, food and beverage distribution and other environments, which can effectively improve space utilization.
Deep-bottomed plates help better display food, especially dishes that need to be displayed in layers or with multiple ingredients.
