Five StarAdvance Small Spiral Notebook, 2 Subject, College Ruled Paper, 100 Sheets, 9-1/2" x 6", Teal (73164)

Does this come packaged or just lose? I don't want pages getting damaged or bent when shipped w/other items.

Can I use a dry erase marker on the pockets of the dividers?

Can you add loose papers, or are you limited to what is already bound in the notebook? 100 pages isn't very much

How do I move the dividers?
