A mobile telephone. Designed against the current trend of making phones ever smaller and less conspicuous. When you use this phone everybody knows about it, they can see you are communicating with someone else, they understand and are not confused or excluded. For example, by people hiding their phones in their hand, or by talking on the little remote earpieces. Off the hook is a commitment to retro design, more so than similar efforts. It is a different take on hands free, you can balance it on your ear and shoulder comfortably to keep your hands free. Off the hook is a design classic resurrected with modern technology.
