This lot of antique/vintage waistcoats is made up of three sets of 6 buttons each -

6) clear (crackle, faceted, frosted) glass in brass

6) milk glass in metal, and

2) green, 2) purple, 2) black glass in metal.

They are about half inch in diameter each. Conditions vary, please refer to photos. I combine shipping charges, so let me know if you'd like an invoice before paying. Thanks!
