The Matsuda - M5007 is a classic round drill-mount style crafted of ultra-lightweight titanium. Rimless construction—an innovation dating to the late 1800s for lighter, more comfortable eyewear—is refined here with hand-engraved details adorning the top and bottom of the beta-titanium temples. Nearly invisible on the face, unmistakable in the hand: the meticulous metalwork of Matsuda's Sabae craftsmen in distinctly modern form. Handmade in Japan. Includes Matsuda box, case, and cleaning cloth.
