Abstract: A storage arrangement for a stack of collectors' cards includes a box with a front wall, rear wall and laterally spaced sidewalls dimensioned to receive the cards on edge in a stack, one of the sidewalls being open at a top. A filing barrier is attachable at a selected position along the sidewall and has a boundary element for engaging against a face of the cards and a clasp attached to the barrier. The clasp engages over the sidewall, which is, for example cardboard, and permits the box lid to be closed over the box sidewall. The clasp is a resilient clamp attachable to the sidewall. The clasp and barrier element preferably are integral parts of a plastic sheet of uniform thickness, the barrier element being dimensioned approximately the same as a card and the clasp defining a U-shape with opposed legs for bearing against an inner and outer side of the sidewall.
