Magical Binder

So two of my classes don't require textbooks.  Sounds awesome, right?

WRONG.

You'd think you'd save money not buying a textbook, right?

WRONG.

In fact, it's not awesome, and it doesn't save money.  No textbook means print a bunch of gazillion-paged articles, so many that you fill a 1"binder, just for the first 3 weeks' readings.

Um...yeah, I'm gonna need a bigger binder, but I hate big binders.  To much space and too heavy.  So, my only alternative is to find a magical binder, one that always has room and doesn't gain weight.  The problem is, if I find one, it would probably never work in my muggle hands.

I think a 4" binder will do the trick.  For one class.  Man...
