The spread of wireless communication is growing. A handy holder provides an innovative cost-effective support for communication devices when controlling movements of people inside or outside of a building. The idea is to use a plastic case capable of repelling bacteria, a case with perpendicular walls adapted to support a small rectangular radio communication such as walkie-talkie radios. In preparing plastic walls, it is important to drill holes for the unobstructed passage of broadcast waves and to provide openings for communication ON/OFF. Perpendicular corners are obtained by carving a width of plastic until there remains a thin wall which may be folded either internally or externally, thereby creating a link to a flared normal direction.
