White+ GOLD Faux Pearl Western Shirt Buttons Not Snaps, Shank Back 13mm / 1/2", Pack of 20 #KB-944
They look like Western pearl snaps, but they're actually shank-back, sew-on, very lightweight, possibly all plastic, buttons. Glowing, lustrous pearly inset is not true pearl shell or glass, they seem like some type of resin or acrylic? Gold-color metal or metal-look rim, backing and shank. Shank opening is around 2mm. Sold per pack of 20-21 sew-on buttons.
