The Matsuda - M3163 is a sleek rectangular frame crafted from high-grade Japanese titanium. Engraved temples add subtle artistry while precious metal plating deepens the refined finish—detail that rewards attention without demanding it. Timeless in design and meticulous in execution, the precision and heritage craftsmanship Matsuda's Sabae workshops have sustained for decades, expressed with subdued confidence. Up to 250 individual steps stand behind each finished frame, patience measured in hours. Handmade in Japan. Includes Matsuda box, case, and cleaning cloth.
