Technically, esrog boxes are a way of beautifying the mitzvah and showing respect and value to a divine commandment. However, I find them repulsive. In this age of excess, they represent a major societal ill. They are examples of keeping-up-with-the-Joneses, mortgaging your house to pay for oversized weddings, filing for bankruptcy but still bidding on kibbudim (honors) in synagogue,... In other days, silver esrog boxes were signs of piety. Today I view them as the exact opposite. That's why my grandfather's esrog box is lying unused, somewhere in a closet in my mother's house. I won't be a party to such attitudes. I'm sticking with the good old cardboard box.
