The image is adhered to a smooth, white Mother of Pearl shell base, then finished with a glossy protective coating that brings out the sheen even more. Natural, iridescent white shell provides a perfect base for the design. Artisan button made in the US by Susan Clarke.  Finest quality, hand made button. May be slight variance due to the natural shell's tone.

These can be hand washed by turning the item inside out first and using cool water, delicate soap and no dryer. Or remove before washing.
