A toothbrush case serving both as an original package case and as a permanent storage-travel case has female and male body members with thin resilient PVC plastic walls that overlap at a detented region for manual engagement and disengagement. The case body members are in a preferred embodiment hollow receptacles defined by four quadrilateral walls and an end wall, with the male member funnelled for ready insertion into the female member. Detent dimples in two opposing side walls provide a snap-lock position in a region where the two body members overlap so that they may be manually engaged and disengaged by means of the resiliency characteristic of the walls. This resiliency absorbs impacts and shocks encountered in storage and assures long life without malfunctioning or breaking.
