This is the RADIOCITY model, a masterpiece metal Boston frame from MASUNAGA since 1905 (Masunaga Optical), Japan's oldest eyewear brand. With its simple and refined design, it can be worn in any situation and is suitable for all occasions. It can be worn by both men and women. It's a simple, rigid Boston style made entirely of metal. The front rim, while slim, has a slight inward bulge like a "strength rim," designed to accommodate prescription lenses aesthetically. The design is smart, with no metal ornamentation, relying on "surface transitions" and "color separation" for its design. Front color: Silver Temple color: Silver Front width: 131mm Front height: 41.5mm ● Lens width: 47mm ● Lens height: 40mm ● Bridge width: 21mm ● Temple length: 145mm Made in Japan Please feel free to ask if you have any questions. #masunaga #masunagasince1905 #増永眼鏡 #ボストン #パント #メタルボストン #radiocity #ラジオシティ #眼鏡 #メガネ #メタルフレーム
