The DVD discusses various linking ring sets, and then teaches how to display the key ring and perform ring flourishes, as well as various links and un-links. There’s also information on storing the rings, linking without a key and other techniques. Daryl also teaches a sample routine that you may use as a foundation for your own.
If you’re just starting out to build your own linking ring routine, “The Essentials in Magic: Linking Rings” is perhaps the best way to begin. I wish that it had been around when I was starting out in magic.
