Winged Wonder. Inlaid with naturally dazzling blue lapis, our solid Brass Fly Box features two wings that slide to the side to reveal small compartments for stashing small treasures. Hand-cast from a clay model sculpted by Jonathan and his team in our Soho studio. Like a fine wine or your favourite leather jacket, our brass only gets better with age. Over time, the polished brass will develop a rich natural patina. If desired, use a microfiber cloth to buff out fingerprints. If you have no patience for patina, use a brass polish.
