You are buying 13 VINTAGE Large Green Acrylic/Lucite PinWheel Design Round Buttons 29mm 1 1/8". They are all a large PinWheel Design thick round button that measures 29x11.1mm. All of these are suppose to be from the 1920-50's, so these could easily be celluloid, bakelite or just plastic of some kind, I don't know how to tell the difference, sorry. These have never been used. They all have a sturdy metal shank and I can see them on car jackets. Smoke and Pet Free. Shipping is free in the US, no overseas shipping.
