A three-piece pocket-size hybrid container for holding a consumer product such as smokeless tobacco product in an interior volume of an inner ring mechanically secured to an interior of an outer base housing including a cover to fit over and snugly around the inner ring. When closed, a cover sidewall may engage a sidewall of the outer base housing to form a flush exterior sidewall of the closed container or the cover sidewall may be spaced apart from the outer base housing to form a gap in the exterior sidewall of the closed container. The outer base housing and cover can be metal and the inner ring can be plastic to provide a strong and robust package that maintains product freshness and is easily opened and closed.
