Zicai is a casting “High Definition (HD) Acetate frame”, an eyewear with internal decorative core with 3D high definition pattern. It is inspired by a traditional Chinese decoration bottle, which benefits by offering outstanding 3D pattern and texture. Due to the unique technique of patented Casting HD, Zicai is more dimensionally stable than usual acetate frames. Therefore, this acetate frame carries out better reliability and comfort properties. Without wire core on acetate temples, the creativity on design is unlimited and the pattern would keep lasting sharp and clear since the color and texture is totally embedded into the crystal clear covers.
