DUN (GUMMETAL)

DUN aims to create the most comfortable eyewear by using "GUMMETAL" in the parts of their glasses that bear stress. "GUMMETAL" is a special titanium alloy made by Toyota that is 10 times more flexible than regular metal. This results in high-quality glasses that fit well and feel secure on most faces.

​

DUN frames have a stylish Japanese design and are made by by one of the most traditional eyewear factory, Sanko Kogaku Co., Ltd (established in 1923). The quality and craftsmanship are among the best in the world.
