I think this will be useful in business and private settings! Extremely beautiful condition. Size: 56□16-131 Lens curve: 4C Height: 29.5mm Material: F: β-Titanium, T: Acetate Price: ¥40,000 (+tax) FEATURE This model pursues a delicate and flexible atmosphere by eliminating as much waste as possible. The β-titanium front is made as thin as possible in the necessary areas, utilizing the springiness of the material itself. Also, to achieve ultimate simplicity, the through-holes that usually hold the nylon thread on the upper part of the front have been eliminated, and the structure is fixed internally.
