Artisanal scented pebble in soy wax (of plant origin, renewable because it is derived from soybeans, biodegradable, without GMOs or pesticides, not tested on animals), without paraffin (petroleum derivative)

Just put a pebble on a burner (available: here ) to melt the pebble and diffuse the scent in the room. A pebble perfumes +/- the room for 8 hours.
Perfume made in Grasse in France.
