Silicone-based resin is added to improve wear resistance to high-strength raw materials, and the slippage quality is greatly reviewed not only on the surface but also from the material. In addition, additives were injected to overcome the weakness of nylon's weakness in lightfastness, which dramatically increased its lightfastness and greatly reduced changes in nature (strong degradation). Here, the pinnacle of improved linear strength power, wear resistance, and resistance is "THE BLACK NL".
