Chocolate Brown Vintage 2.2cm French Buttons - 6 or 24

A smooth chocolate brown, a shiny surface.
Interesting design  too- a fluted circumference and holes cut out to show the colour of the fabric underneath.
They are 2.2cm wide, French, 1940s, and I'm selling them in lots of 6 or sheets of 24.
The last photo shows the back of various colours of these buttons.
