Hi Niccol. Yes you can use E/O's with your beads and you do not have to use our oils. We do however test our oils so we know they do work. Some get done fast and others take a while longer. E/O's work a bit differently. They do not last as long and you must monitor them when putting the oils in, because they cure quickly and you may not have notice as you walk away for a few hours. Use DPG as a carrier to help smooth the oils out so they do not harden.
The directions are online so you can print them as you need them.
