You are buying 30 Vintage Clear w/  Solid Gold Edge Matching 2 Hole Czech Round Buttons 18mm (11/16"). All of these are 2 hole buttons. There are the same size and shape measuring 18mm (11/16") and are a nice thick 5mm. 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 and they are two hole buttons. 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.
