What is the difference between Smooth and Crepe exam paper?

Im looking into buying some exam paper but I'm still new to medfet and not sure which one to get or what the difference is. I really like what my doctor uses, its that thin paper that crinkles when you sit or lay on it. Is that smooth or crepe? Also, which lenght and width do I get? You don't have to be a doctor to buy exam paper right? Dumb question, I know I'm just still pretty new.

Well in my opinion, don't get the crepe paper, I just bought a case and hope i can return it. It is like tissue paper, tears too easy and sticks to the patient.I think the best would be the smooth.

The smooth is the best, very crinkly, thin and slippery. So erotic to lay on or play doctor on. I just posted a pic of my favorite kind of exam table, the kind I laid on at my pediatrician-flat, wide and high enough that for a rectal exam you had to be on your stomach or side instead of bent over.
