You are buying 12 Vintage Gold, Silver &Black Czech Round Buttons 18mm (11/16") to 24mm (1"). Most have matching buttons except for the large black ones, they have different designs. They are all round and measure between 18mm (11/16") to 24mm (1"). These are all vintage Czech glass buttons. I bought a huge tub of vintage buttons, I had plans on selling them at the shows but did nothing with them, so I sit down and grouped like buttons. Great for a collector, with glass and metal shanks. These have never been used. Please look at all the pictures, you are bidding on exactly what is shown. Smoke and Pet Free. Shipping is free in the US, no overseas shipping.
