Chewing Knob

Chewing Knob is a fully integrated feature of the latest mobile phone protective case. It's conveniently located in one corner so that you can get it into your mouth and chew on it while talking on a call.

Made from a tough rubbery material, Chewing Knob is durable, easily cleaned and will last a long time, but a periodic exchange system will replace it for a modest maintenance fee if it gets worn out through excessive chewing. Now you can grind your teeth and make a variety of awkward slurping sounds when responding to pesky nuisance calls.

Inevitable delux version features a reservoir of refillable flavours built into the phone casing that are delivered to the Chewing Knob via a sucking action.
