I base my decisions on the person not the papers the snake comes with, as a result I think only my snakes I got from Justin Kobylka actually came with documents. Which is cool because Justin is great and I trust him 100% so the papers had nothing to do with my decision but was a nice touch. With the exception of my Butter that I got from NERD all my other animals came from guys I met and talked to and snakes I could handle and inspect before buying.
