Gorgeous Vintage Glass Buttons.

I found these in a box with other cards of glass buttons - with French labels.
They are glass, 2cm in diameter and have a glass shank with a single hole, moulded into the back of the button.
Please have a look at the other unusual old buttons and haberdashery items I have listed in my ebay shop this week - all unused stock from old haberdashery warehouses. 
I always give a good combined shipping price for multiple purchases - just ask me for a combined postage invoice.before you pay.
