Cool Hunting

New from London-based design group oki-ni and world-famous Japanese graffiti artist Daisuke Sakaguchi, these street-lux mobile phone accessories are made from "hallmarked" sterling silver and attach with a plastic-coated stainless steel wire loop. Like Daisuke's jewelry and belts, the four designs (see more after the jump) look something like 3-D interpretations of the artist's graffiti—though these are a more pared-down, elegant gesture. Each piece comes with a one-of-a-kind display that features Daisuke's tag. Available exclusively from oki-ni, the accessories start at $168.
