Iridescent grays and silvers. Natural Black Lip Mussel shell in a shank back design. Real natural shell; no two are alike as you can see from the photos. All have a subtle crackled mosaic/stained glass look. There is a clear satin coating over the shell, so they are smooth, strong and sleek. 15mm / 5/8" diameter. Shank opening is 3mm and the back is bright white real shell. $3.45 per button.

No hot water, no harsh detergents and no dryers. Probably best to remove them before dry cleaning.
