The Vanderbilt was made in a limited production run with 100 pieces in each color and there now exist less than five frames in the Havana Tortoise/18k Gold making it truly an exclusive and one-of-a-kind model. It is a bold, yet thinly silhouetted titanium frame that uses modern engineering to create a familiarly sophisticated look. The style and name lend itself to our continued accolades to fine collegiate establishments. Highly intricate multi-dimensional laser etching applied to the titanium and rim wire, with high quality enamel insets. 100% pure titanium plated in 18k gold combined with Japanese cotton-based acetate temple tips and a hidden spring hinge.
