35 base shanks ready and available to start your rings. I've tried to provide a variety of base shanks that may be common. Each one has selection sets so they are easier to adjust once you import them in from your library. They can save you time and are an easy way to create rings when you don't want to start from scratch.
This video shows how to make a full ring from parts in your libraries. I will make another one soon to specifically show just the shanks. For now here is a quick rundown of the process.
