What is the meaning of set of box?

Excuse me, could you please clarify what you mean by the phrase "set of box"? Is it referring to a collection of physical boxes, such as the ones used for storage or shipping? Or is it perhaps a metaphorical term used in a specific context that I'm not familiar with? Without more context, it's difficult for me to give an accurate interpretation of this phrase. Could you please provide more information about the context in which it was used?
