High-Quality Stainless Steel Material: Made entirely of stainless steel, with a thickened and brushed electroplating process, it is durable, anti-oxidation, and has a long service life.

Low Friction and Low Noise: The solid thickened steel bearing is tightly engaged with the hinge shaft, making rotation more stable, reducing noise, and minimizing wear.
