The Oyster is designed with Maine Midcoast roots in mind. Moody cold hues of the Atlantic and the ripples of the beautifully resilient Oyster. Mango wood with 14k gold-filled posts. 1.5 in. Binky & Lulu believe in the power of craftsmanship to be evident in each and every design. They find inspiration from nature, popular culture, travels, art periods and life experience.
