This is the Ricoh GR IIIx Original PURPLE Ring Cap. This ring cap is made of aluminum alloy with a luxurious purple anodized finish. It adds a touch of personality as an accent to the lens. By replacing the body-mounted ring cap GN-2(BK), you can enjoy a special GR IIIx. *Not for sale I tried it on, so it's not unused, but I never took it out for shooting, so it's in good condition.
