M3124 Sunglasses by Matsuda. Color: Brushed Gold / Black Grey, Brushed Gold/Milk White / Brown Gradient, Tokyo Tortoise/Brushed Silver / Sage Green, Rose Gold/Bordeaux / Pink Gradient, Size: 51-23-142. The M3124 are contemporary sunglasses with a Matsuda twist: a TV-cut acetate insert and delicate titanium temples contrast beautifully with a bold rectangular lens in bright Japanese acetate. The unique design is complemented by expert craftsmanship; each piece is crafted by Japanese artisans using hand-polished acetate, hand-applied lacquer and precious metal finishes. It's a one-of-a-kind accessory for the trendsetter.
