High School and College Transcripts

So, for those of you with completed packages, did you guys send your official transcripts in their envelope or did you open the sealed envelope?

If you opened them, did you two hole punch them?
I don't want to two hole punch my evidence, can i use acco clips?

I don't know if people are sending unofficial transcripts. I think it would be better to send everything official but I will leave this for others to answer.
