A container for a stack of sheets (e.g., abrasive coated discs) including a base portion adapted to extend transversely across a bottom surface of the stack of sheets and having opposite ends adapted to be positioned at spaced locations along a side surface of the stack of sheets; and a plurality of stiff elongate retaining portions having proximal portions attached to the base portion at its opposite ends with the retaining portions at spaced locations around the side surface of the stack of sheets. The retaining portions have central parts adapted to extend along the side surface of the stack of sheets from its bottom surface to its top surface at those spaced locations, and have distal parts adapted to extend above the top surface of the stack of sheets. Those retaining portions are positioned or bendable to position the distal part in contact with the top surface of the stack of sheets, and have a shape or retain a shape to which the retaining portions are bent to retain the stack of sheets in the container.
