This half-frame retro style buffalo horn glasses are made of natural black yak horns. Yaks mainly grow in the Qinghai-Tibet Plateau region of China. The whole body of yaks has dark brown, or white long hairs. The yak horns are hard and dense, and generally have obvious texture is one of the best materials for making horn glasses.

The retro shape of the round frame is obviously wider than other parts of the bridge, just like an ancient stone arch bridge, adding a retro style. The half-frame design makes the horn glasses lighter and suitable for long-time wearing.

The unique double-rivet hinge is made of elastic metal, so the hinge also has good elasticity, allowing the temples to expand outward, absorbing the pressure from the front frame to the greatest extent, and making it easier to wear.
