Only Margiela could rework keys and produce something this creative having created three impressive items with a key ring, key chain and key money clip. The key ring impresses me the most, having taken a house key cast in brass and dipped in white rubber. Then there is the chain, which is more of a rendition with the brown leather key fob with four separate silver metal key rings each with a leather head cover, three of the head covers are embossed with gold lettering Home, Parking, and Office. Finally the money clip, so simple yet so interesting and well executed.
Thanks to This Heart Is On Fire for the info.
