The Rubbermaid Cup Holder Organizer instantly adds storage space around your car’s existing cup holder, with plenty of room for your cup, bottle or handled mug in the center. The central opening holds cups, bottles and handled mugs, while the two side compartments keep smaller items such as cell phones and mp3 players organized and within easy reach. The pass-through for power cords makes charging your electronics on-the-go a breeze. The Cup Holder Organizer fits most console cup holders and is dishwasher safe. To clean, wipe the surface with a soft damp cloth or place in the dishwasher.
