Ohekai Bamboo Sunglasses
Ohekai uses bamboo for their sunglasses. Bamboo is one of the worlds most versatile and eco-friendly organisms. Unlike trees, bamboo only takes 3-5 years to reach maturity and can be harvested every year. Bamboo is also strong, having greater tensile strength than steel and can withstand compression better than concrete! As a bonus, if you lose these glasses in the water, they'll float, unlike your plastic or metal ones.
