Each button has its metal screw, included in the plastic or in the crimping metal. Size : Buttons unclogged Diameter: 15 mm (also exists in 14 - 14.5 - 16 - 17 - Basses: 7.5 - 9 - 9.5 mm) If you do not specify anything, buttons in diameter 15mm white, not high with red felt. If you want another type of button or a different color, you should specify it when ordering. Without these details, I send the single white buttons in diameter 15mm with red felt. I couple the shipping costs (with the single buttons in particular), let me couple the costs before paying your purchase, thank you. If you need technical advice, please consult the FAQ as well as the "tips and tricks" of our AtelierLoffet site ATTENTION : By default, the buttons are white, not high (simple) with red felt. Without thes.
