The patented screwless hinge design of this new eyewear series, developed by the design team, draws inspiration from the traditional Eastern mortise and tenon structure. This innovative design enables the temples to open and close to 180 degrees, adapting to different face shapes and reducing breakage risk due to external pressure or pulling. Moreover, this design enhances the product's durability. The eyewear frame comprises 0.6mm bio-thin steel or corrosion-resistant titanium alloy, weighing only 16g for a lightweight wearing experience.
