The heart retainer is the latest innovation from Kaos Softwear in body piercing retainers. These are especially useful for, but not limited to nostril, monroe and cartilage piercings. The flesh tone colors run from lightest (v1.0) to darkest (v5.0). By pinching both sides of the 'heart' together it collapses, creating an extended reach for an easier insertion. Once the retainer is inserted the 'heart' will open to create a flare, holding the jewelry in place. Kaos made a great little video to demonstrate insertion and removal .
