The Enlarging Crescent are a great way to stretch your piercing at a slower rate. The Crescent that you start off with will be depend on what gauge you are now. For instance of you have a 10 Gauge piercing you would want to start off will the Small Crescent, but when you finish stretching over time with this piece your piercing can be as large as a 4 Gauge. The key to make you piercing large is to go slowly when stretching, because you never want to tear your piercing because it will cause recurring issues to you in the future and also scarring that will take away from your piercing.
