The word "product" refers not only to things that are sold, but also to things that are produced (made, fashioned, fabricated, etc.).
This is as close as I get: https://en.wikipedia.org/wiki/Product_(business)
And it says:
> In marketing, a product is an object, or system, or service made available for consumer use as of the consumer demand; it is anything that can be offered to a market to satisfy the desire or need of a customer.
Sounds like something you'd buy?
