Inspired by two geometrical configurations, these Boston-style sunglasses have a strong presence and are designed to snuggle up to the human face as part of it.The front surface shows a flat and sharp expression with little unevenness, and in contrast, the back side, which is closer to the human face, features soft lines with dropped edges.Delicate finishing by craftsmen's handwork coexists with a clear and modern impression of geometry and comfortable wearing comfort.
