2 or 4 Vintage 8.5cm Tortoiseshell Wave Hair Combs

They are made of a tortoiseshell plastic which glows when it catches the light.
They are decorated with delicate little waves along the top - Very Deco.
And on a more practical front they have slightly waved teeth to make sure they stay in your hair.
They are 8.5cm long and 4cm tall, are slightly curved, and remarkably effective at keeping hair where you want it to be...
I found several boxes of these in an old warehouse I cleared, so in excellent unused condition.
The price is for  either 2 or 4 of these hair combs.
