I use J223/soy blend. Have tried other container wax but go back to this. I buy most of my Fos from Alabaster since I can pick them up. So far I have been very pleased with all the Fos I have purchased. Kuduz, pumpkin spice, caramel apple pecan, blueberry pie, magnolia, mulberry, pomergranate are some of my best sellers for this time of year. When you visit they have the Fos so you can smell them. Their customer service is excellent.
