This is a pack of trading cards.
A 40 mm binder with three standard openable D-shaped rings spaced 10.75cm (4-1/4 inches) apart. Comes with 10 pages of 9-pocket plastic filing pages designed for trading cards that will hold up to 90 cards if you organize them with front and backs visible, or up to 180 cards for one-sided filing. Big enough to handle a few dozen more pages of additional filing sheets as your collection grows! Four colors available (linked below).
