3 Black Curved w/ Metal Shank Toggle Vintage Coat Buttons

3 vintage toggle coat buttons with metal shank in a shiny black. I'm not sure what the buttons are made of - maybe a mixture of wood and plastic. They are slightly curved in a tube shape.

2 buttons are 1 7/8 inches long (outer curve) and 1 button measures 1 3/8 inches long. Other than a few scratches, they are in good used condition with no cracks or chips. See pictures.
