These heart front plugs I designed with about a 7/16" wearing surface so they are perfect for someone with thicker lobes as well as thin. They can also be worn in flat/helix, conch and other piercings. These are grooved for a silicone o-ring and well rounded with no sharp edges at all! Perfect little cuties for your lobes and other piercings. These come in 8g through 1/2".
