Every order includes complimentary, fully insured shipping delivered securely to your door.\u003cbr\u003eDeep Cultural \u0026amp; Historical Background\u003cbr\u003eDuring Japan's Showa period post-war industrial revival in the 1950s and 1960s, precision optical workshops flourished throughout Tokyo and Osaka. Shinko Seisakusho Co., Ltd. gained recognition for engineering clever pop-up pocket optics for international export. Named the \"Turtle\" for its protective hard-shell folding casing, the design incorporates a spring-tensioned internal mechanism that collapses into a pocket profile less than an inch thick. Manufactured using pressed steel stamping, vinyl cladding, and precision ground glass lenses, these portable sports and theater glasses reflect the innovative spirit of mid-century Japanese consumer electronics and industrial craft.\u003cbr\u003eCondition \u0026amp; Surface Character\u003cbr\u003eThis piece remains in functional vintage condition with an attractive, time-earned surface character. The textured terracotta leatherette exterior displays honest age wear, edge rubbing, and surface finish loss along high-contact points, revealing the underlying material beneath. The chrome-plated steel frame retains good luster with minor vintage oxidation. The spring-loaded pop-up release catch functions smoothly, locking the protective lid shut when folded. The top thumbwheel focus dial turns cleanly to adjust the optical assembly. The glass lenses are intact without cracks, displaying minor internal dust and light surface wear appropriate to vintage optics.\u003cbr\u003eDimensions, Shipping \u0026amp; Display\u003cbr\u003eHeight: 2.5 inches (Open position)\u003cbr\u003eWidth\/Diameter: 4.2 inches\u003cbr\u003eDepth: 0.7 inches (Closed case profile)\u003cbr\u003eWeight Profile: Light \/ Compact (Steel Chassis \u0026amp; Leatherette)\u003cbr\u003eShipping: Free Standard Shipping (Fully Insured \u0026amp; Securely Boxed)\u003cbr\u003eMounting\/Display: Display stand and decorative background props not included.\u003c\/p\u003e","brand":"Belle Afrik Arts","offers":[{"title":"Default Title","offer_id":60049563320606,"sku":"BA-0039","price":35.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1081\/5176\/7326\/files\/il_fullxfull.8567861612_tvj2.jpg?v=1790371114","url":"https:\/\/belleafrikarts.com\/products\/vintage-turtle-shinko-seisakusho-folding-opera-glasses-japan-pocket-binoculars","provider":"Belle Afrik Arts","version":"1.0","type":"link"}
