12L Two Hole Pearl Shell Dome Top Dimi Buttons

Set of eight vintage Mother of Pearl sew-through shell buttons. Each button measure approximately 7.3mm at the widest (rounded up to 12L, 7.6mm, or 19/64 inches). The dome is approximately 5 mm in height. Truly unique, these flat bottom, dome-shaped buttons have a round, deep recessed eye with two holes. 

A natural material, Mother of Pearl is made from nacre (the inner layer of pearl oyster shells). These buttons are prized for their natural luster.
