How to send a letter with C/O?

[Urahara02]

I Know c/o is "care of"

but say im addressing the letter to a sports team how would i address that?
also what if i was sending more than one player a c/o letter would they be different envelopes?

Sorry alittle new at ttm any help is appreciated.

Here's an example for you:

Dirk Nowitzki
c/o Dallas Mavericks
2500 Victory Ave
Dallas, TX 75219


I would definitely send each request separately

Hope this helps!
