I love Palo Santo, it's so evocative of California for me, it's forests, deserts and oceanic coast. It begins as a fresh resinous scent and tapers into something deep and earthy. In Japan they have word for 'forest bathing 'shinrin-yoko' that encapsulates the sense that palo santo brings to a room in any season. I love that Fenix is an Irish company! If you are sensitive to scent this can be quite heady. I found the thin stick was plenty for a medium sized room, I think I would use the thick stick for a very large space or in an outdoor setting.
