Piratelab 9-Pocket Binder (Black)
"Pirate Lab card binders are crafted from crush-resistant polypropylene. A hard-formed spine, three metal reinforcing rivets through the center seam, and a heavy-duty 1" elastic closure give your cards ultimate protection.
Card binders are a perfect fit for unsleeved cards from many major collectible card games, like Magic: The Gathering*, Pokemon*, and Yu-Gi-Oh*. This binder holds eighteen (18) cards per double-sided page for a total of 360 cards."
