----Comparison ---

A common bowl has only ONE layer of wall.

A Soupér bowl has 2 layers of walls.
The outer wall is specially constructed with a ring, rolled inwards, to create an air gab between the walls to serve as an efficient insulator. This outer wall we called Soupér Sleeve

* Notice the air gab that serves as an air insulation between the bowl and the sleeve.
