Ultra PRO's Eclipse line uses a sideloading pocket design (cards slide in from the side, not the top) specifically to stop them from falling out when the binder's carried around — a small detail that matters more than it sounds if this is going to game night in a bag. This 2-pocket version holds 80 cards double-loaded, with an embossed black web pattern that frames each card, and an elastic strap to keep it shut in storage. Jet Black.
Need more room? The 4-pocket and 12-pocket versions are in the same line.
