A multi-pack assembly for containing and dispensing one or more new pen needles, and receiving and containing used pen needles after use, is provided, wherein a plurality of both new and used pen needles can be contained in a series of storage vessels, each secured to an adjacent storage vessel thereby forming an easily managed multi-pack assembly shape, and providing caps for each individual pen needle storage vessel to provide a sterility barrier and which can be opened independently of one another, and which can be closed in the same manner after use to prevent unwanted interaction with the used pen needles contained therein.
