[General] Individual item or items?

[ardel]

I'm a bit confused about the usage of "individual" with nouns. Is it individual items or individual item?
For example: "The box also includes an envelope that contains additional information about individual items and products." Is this correct?

It is either "individual items" or "an individual item".
