Charcoal Gray Rustic 20mm Floral Shell 13/16" Pack of 4 Buttons, #23-215

These Mother of Pearl 2-hole buttons are glowing charcoal with subtle blue violet sheen and almost-black edges. They are laser- etched with a teeny floral pattern. The design looks Balinese - these may be from Bali. There is variance in the etching and colors of iridescence; size is quite consistent at 13/16" or 20mm.  Holes about 2.25mm. A bit rustic, thin, strong two-hole buttons. Backs are mottled dark brown.  Sold per pack of 4.
