There are many brands available. Give your local print shop a call. They can probably sell you a small quantity of what you want. If you ask, they'll even 3-hole punch it for you. Be sure you tell them that you want to be able to write on it. I say that because Xerox has something they call Nevertear which is made of stuff which will not accept pencil and regular ball-point ink will smear. You can only write on it with markers. It is probably more expensive than some of the other stuff out there. I will check with a couple of my friends in the business and see if they can jog my memory about one kind of paper in particular I used to use.
