Citrus Floral Scent 8″ Incense sticks are made in-house, which we roll with wood powder and gum resin, without charcoal. The finished sticks are then dipped into our proprietary fragrances, which have been blended with pure essential oils. We use eco bamboo sticks, handmade paper outer packing made from recycled cotton and recyclable double inner bags for best aroma retention. No Charcoal and No Phthalates. Burn Time:45 Minutes
