Blake Kuwahara Portman Sunglasses

Blake Kuwahara's signature is the frame within a frame — an inner silhouette encased in an unexpected outer shape, two distinct frames seamlessly fused into a single sculptural form. Each model is named for an architect or designer whose work informed the geometry, and every piece is handcrafted in Japan.
