♦ Description: a very rare metal-in-metal boston model that combines a metal rim inside the rim. it is a conceptual design that the gold color of the inner rim shines casually by the angle. in order to finish as thinly and casually as possible, we use bespoke β titanium for inner rim parts. while following classical elements such as the upper part of the bridge with an edgy silhouette called "tenkaku", keyhole cut at the bottom of the bridge with a keyhole motif, and a milky white color pad, the front parts are finished in a retro future model by integrally molding the front parts with a clean look.
