- Collection:IMAGINARY LINES - A combination of 100% pure titanium and beta-titanium. A sharp almond shape characterizes Human, a recent addition to our IMAGINARY LINES collection, adding new flavor to a classic female style, offered in both primary and neutral hues. The radically pointy shape creates a unique, uplifting expression in the wearer, while soldered drop end pieces and bridge in high quality titanium ensure a robust foundation to this delicate frame. Silicone nose pads and end-tips ensure comfort and minimal temple design in this exciting female style.
