70s USA-made AMERICAN OPTICAL SAFETY. "Fresh," a popular champagne-like color even now. This particular piece has a sophisticated, alluring color. This frame color in good vintage condition is quite rare. The frame is stamped "AO FLEXI-FIT 6M Z87." There are no side shield attachments or holes. The lens color is a compatible dark green, like G15. Smaller sizes are occasionally seen, but this size is the best for sunglasses: 48, and the bridge width is 23, considered to match the height of Japanese noses (golden size 48/23). Front width is 142mm, temple length is 145mm. The condition is good vintage. Recommended for those seeking a high-quality, authentic piece – a once-in-a-lifetime opportunity. bys eyewear B&L Bausch & Lomb SHURON RAY BAN Hakusan Megane Kaneko Optical julius TART OPTICAL arnel uss moscot lemtosh 50s 60s OLIVER PEOPLES blanc eyevan 7285 bj classic native sons wacko maria windandsea neighborhood doubletaps wtaps Kunichi Nomura Shuhei Nomura Yosuke Kubozuka Kimutaku Tomoya Nagase Daiki Tsuneta Ren Yamada sorry a bootleg supreme boys of summer biker shades goggles military Wellington UV protection culture bank camping damagedone, etc. - for those who like these brands/styles.
