An unusual vintage (1984) solid 9ct gold retractable toothpick by makers William Manton. 
It has a lovely weight to it, just shy of 7 grams and has been given a gold jump ring, making for easy wear on your favourite chain. 
Whether you just like the novelty of the item or are wanting it to be the fanciest way to use a toothpick - this lovely example will take pride of place in your collections. 
The toothpick can be twisted one way to extend the pick and twisted in the opposite direction to retract it.
