What is an example of a kit item?

Excuse me, but could you please clarify what you mean by "kit item"? Is this in reference to a specific industry or context? For instance, in the world of finance and cryptocurrency, a "kit item" might not be a commonly used term. However, if we were discussing a startup kit for cryptocurrency traders, an example of a kit item could be a guidebook or software that helps users navigate the complex world of digital currencies. Is this what you had in mind, or were you referring to something else entirely?
