We are introducing our line of stylish sunglasses. These have DTB ( short for Downtube ) printed on the side, removable lenses, removable nose piece, removable cushioning for the ears. They are up gradable with foam padding to keep salt water out, and prescription insert ( if necessary ). You will not find a more stylish set of glasses, we sourced these from one of the top Taiwanese high end sunglasses manufacturers. Several brands have sold these same frames for well over $100.
