Palo Santo Wood Pressed Incense CartonPure Bursera Graveolens incense, from forests managed, authorized & certified by the Ministry of Agriculture and Irrigation of Peru in Piura (SERFORPiura). The smell is intoxicating, smokey and cleansing. I like to break them in half and use a small piece at a time to savor their existence. Each carton contains 12 boxes which hold 4 pieces. Burn on a safe, heat resistant surface and with care. As with any burnable there is potential fire risk.
