This is a popular 70s USA-made AMERICAN OPTICAL AO FLEXI FIT. This model, with its AO hinges and keyhole bridge, is instantly recognizable as American Optical, and the black frame is a very popular model. It's a model that's hard to find these days, but this is a deadstock item. Please understand that there may be minor scratches due to its vintage nature. The frame side is marked with "AO FLEXI-FIT 6M" and the print is still visible, indicating that it has been stored unused. There are no side shield attachments or holes, making it a perfect model for everyday use. This item has custom UV color lenses made in Sabae, Fukui Prefecture, so you can use it immediately upon arrival. Size: 48□22 (Golden size) Color: Black (Rare black frame) Lenses: Silver Gray (Can be used both day and night, a light color that can also be used as glasses.) Returns and exchanges are not accepted to prevent swapping. I also have other American Optical items for sale. #byseyewear Please feel free to contact me with any questions. bys eyewear B&L Bausch & Lomb SHURON RAY BAN Hakusan Megane Kaneko Optical TART OPTICAL arnel julius uss moscot lemtosh 50s 60s OLIVER PEOPLES blanc eyevan 7285 bj classic Gou Ayano native sons wacko maria windandsea neighborhood wtaps vintage Nomura Kunichi Nomura Shuhei Yosuke Kubozuka Kimutaku Tomoya Nagase Daiki Tsuneta Ren Yamada sorry a bootleg Johnny Depp supreme boys of summer Biker shades Goggles Military Wellington UV protection culture bank
