The Matsuda - M1040 offers a refined take on the classic rectangular frame, blending hand-crafted Japanese acetate with a precision-engineered titanium inner rim. Intricate detailing and premium metal finishes distinguish each pair, structure and ornament working in quiet partnership. Timeless design balanced by subtle modern touches—the artistry and durability Matsuda's Sabae craftsmen have refined for decades. The titanium inner rim reinforces the acetate front invisibly, strength built in where it never shows. Handmade in Japan. Includes Matsuda box, case, and cleaning cloth.
