Choose your favorite game themed button! Options include domino, dice, suits, and more! Top left is an early plastic, maybe Bakelite. Top right appears to be a bead turned into a button. Middle center is dice with a leopard print background (very Viva Las Vegas). Some are plastic and others are plastic and metal. These measure between 8-28mm / .32"-1.1". Choose top, middle, or bottom and left, center, or right.
