Kirk Originals' Mason round frame sunglasses in black acetate with green gradient lenses are the ideal selection for artists and architects of style. Made in England and slightly oversized, the sunglasses are tactile, engaging and shows the skill of our artisan makers in the curved aspect of the frames. Truly impressive, it takes 72 hours of work on each individual frame to produce this level of handmade quality. They'll look as great in an open top vintage car as they will when peering over them upon arrival in London's best hotels for the weekend in the city. Clean and modern referencing the best dressed men of decades past, Masons are sunglasses to be treasured.
