Opal Ghost - with notes of moonflower, lemon, juniper Eighteen charcoal incense cones wrapped in beautiful handmade paper and tucked into a sleek gold slide tin. Handmade papers may vary. Each cone burns approximately 20 minutes, and with a charcoal base (instead of wood), you'll experience a cleaner burn and less of the typical 'burning wood' undertone. Hand-crafted in small batches at the Revelrie Arts studio, nestled quietly in California's Sierra Foothills.
