Shiny Metallic Grey 1.7cm or 2.2cm Vintage French Buttons

A metallic shiny grey colour and  a lively design - a fluted circumference and cut out round holes.
Made of vintage plastic, French, 1940s .
I have them in either 1.7cm or 2.2cm wide and am selling them in lots of 6 or sheets of 24.
The last photo shows the back of various colours of these buttons.
