When typing a business letter and you have an enclosure do you...?

Question

If you have an enclosure...does the word "enclosure" refer to one item or can it refer to several items.

For instance...if I am enclosing 7 photos with my letter should I put "enclosure" at the bottom or "enclosures?"

Just wondering which one is correct or if both uses are correct.

Thanks in advance.

Answer 1

You should put:

Enclosures (7)
