Matsuda Vintage Handmade Black Metal Tortoise Oval 。This is an authentic pair of vintage MATSUDA model 2904 sunglasses, expertly crafted in Japan. A quintessential piece of 1990s eyewear, these frames showcase the meticulous construction and intricate metalwork that define the Matsuda legacy. The design features a classic oval silhouette pairing rich tortoiseshell-patterned acetate with ornate, scroll-work metal detailing. Specifications: Brand: MATSUDA Model: 2904 Origin: Made in Japan Size: 44-20 145 Lens Tint: Warm Amber Condition: The sunglasses are in overall Excellent vintage condition. The hinges are fluid and operate perfectly, and the lenses appear to be free of scratches. The frames are constructed from a premium blend of metal and cellulose acetate. As this is a vintage item, the acetate and metal surfaces show minor surface wear consistent with age, which presents as a slight dullness or need for buffing. This is purely aesthetic; a professional optician can easily polish these to restore their original high-gloss luster. I have performed a light cleaning of the frames and lenses but as I am not a professional, I did not want to perform a more in depth polishing. Note: The original case is not included; however, a protective case will be provided to ensure the sunglasses arrive safely.
