Key Ring/Coin Holder - Bon Bon Silver - Alessi

Bon Bon is an egg-shaped key-ring/coin holder, designed by Francesca Amfitheatrof, which opens and closes in two symmetrical halves. The inside of the small egg is designed to hold a coin or a token, always handy: for the shopping trolley, parking the car or buying a newspaper.
The two halves of the egg, hinged together, are made of stainless steel half shells inside, the slot for the coin is made of thermoplastic material, inside the slit there is a spring to 'hold' the coin and prevent it from accidentally falling out.
