A package includes a cavity having a series of cavity slots transverse to the cavity's longitudinal axis. These slots permit a pair of stop plugs to be positioned to receive products of different lengths. Each stop plug has four lateral lugs for engaging the cavity slots to resist linear and rotational displacement of the stop plug. Each plug has bottom, end, and side walls to isolate the product end from the cavity. In addition a pair of fingers extending from the stop plug elastically grips the product to further restrain product movement. The fingers can flex to accommodate different sizes of products. A retainer snaps onto the cavity to close it. The retainer includes a retainer stop at each end that extends into the cavity and prevents the retainer from shifting even if the retainer is lifted due to product pressure against the retainer during shipping. The retainer also includes a pair of product restraints extending into the cavity to limit motion of the product toward the retainer. The product restraints are shaped to also provide finger wells for aiding the removal of the retainer when the package is opened. Retaining slots in the retainer cooperate with a top lug on the stop plug to further hold the stop plug in place when the package is assembled.
