Add beeswax, carrier oil of choice and butter of choice to a Pyrex measuring glass. Place in microwave, and melt in 20-second increments until all is melted. Stir well. Add fragrance or essential oil, and stir well. Pour into push-up stick (such as a lip balm-type container) or deodorant containers and let harden overnight. Note: Cocoa butter will make a slightly harder product; Shea butter will make a slightly softer product.
