These lovely two tiered shank buttons are made of a cream resin, the metal shank back is sunk into the material. The shank stands about 3/8th's of an inch off the back face of the buttons. The face is smooth and is 5/8th's of an inch across, the flutes are textured measuring 1/8th of an inch across and the edges are smooth measuring 1/8th of an inch as well. The total width of the buttons is 7/8th's of an inch across.
Each set includes eight total buttons.
These are some of the surplus lot I got in LA last year, I hope they are destined for good projects!
