Artisanal Craftsmanship & Structural Architecture
- Stepped Rim Sculpting: Hand-polished by skilled craftsmen, the bold acetate front features layered stepped bevels around the outer rims and bridge, delivering a distinct three-dimensional geometric profile.
- Electroplated 3+2 Barrel Hinges: Reinforced electroplated metal 3+2 hinges undergo extensive open-and-close durability testing to ensure long-term stability and smooth temple folding.
- Premium Cellulose Acetate Construction: High-density glossy black acetate is tumble-polished to achieve a sleek finish, ensuring structural durability and skin-friendly wear.
- Premium TAC Lens Technology: Fitted with high-clarity dark grey TAC lenses that block 100% of harmful UVA/UVB rays while delivering sharp visual contrast and effective glare reduction.
- Sculpted Ergonomic Nose Bridge: Smooth, integrated nose contours distribute frame weight evenly across the bridge for pressure-free, non-slip comfort.
