A ring binder assembly includes a folder comprising front and rear flaps interconnected by a spine, a pair of low-profile receptacles attached to an inner surface of the spine, and a ring mechanism whose tubular rivets have mushroomed feet designed to be seated in the receptacles. The receptacles open in opposite directions so that the ring mechanism is installed with a swiveling motion. A method of shipping the binders, unassembled, is to place a stack of a number of folder opened flat in a box, leaving just sufficient head space for a corresponding number of ring mechanisms arranged side-by-side in a single row at the top of the box. The binder assemblies can be quickly completed by the retailer, or by the end purchaser.
