Incense quickly transforms a room: transformative smoke uplifts the space while our signature scents linger for hours even after extinguishing. PF Candle charcoal-based Incense is hand-dipped in-house using fine fragrance oils and dipropylene glycol (DPG), a synthetic base commonly found in body care and home fragrance products. Each stick burns for 1 hour; depending on room size, scent longevity lasts between 2-4 hours. 15 sticks in a plastic sleeve inside of each kraft package, measuring 10.75" long each.
