Located in the flat area of cartilage below the upper rim of the ear (the helix) and the flap of cartilage where the rook is located, the flat piercing provides a large area for unique piercing placement. It looks fantastic on its own or combined with other cartilage piercings, like the forward helix or auricle.
However, the flat piercing, like other cartilage piercings, is not an easy piercing to get. Cartilage heals differently than other fleshier areas. Blood flow is an essential part of healing, and since cartilage is avascular, it takes a long time to heal.
