Made from thick black-lip or smoked pearl oyster shells harvested in Pacific coastal waters, they are prized for their deep silver-grey iridescence.
The Challenge Button Company was a major manufacturer of shell buttons, operating factories across the American Northeast around the turn of the century. Workers cut, shaped, rimmed, and drilled imported shells into uniform sets. Durable and lustrous, buttons like these were used by tailors on silk blouses, Victorian vests, and lightweight wool suits.• Packaged giftable
