Blue Pearl's Resin Incenses are collected from the saps and barks of various trees of the Far East. Their use is as old as civilization itself. Burn over charcoal on a censer, or over a stove burner on low heat in a pan used only for incense-burning. Enjoy these uplifting and purifying fragrances, and remember: in days long ago these drops of rare resins were considered as valuable as gold itself. This Prepack contains 7 each of 9 resin varieties and a display.
