Abalone Shank Back Shell Button 5/8" 15mm Blues/Greens # L66594
Green Blue iridescent Abalone shell in a shank back design. Real natural abalone; no two are alike as you can see from the photos. Some have purple, silver or tan tones too. Some have a subtle crackled mosaic look. There is a clear satin coating over the shell, so they are smooth and sleek. 15mm / 5/8" diameter. Shank opening is 3mm and the back is bright white real shell. $4.25 per button.
No hot water, no harsh detergents and no dryers. Probably best to remove them before dry cleaning.
