The sets include a wonderful selection of luxurious home fragrances in refillable diffusers. The fragrance intensity is adjustable. The more reed sticks are being used, the stronger the scent experience. Available scents are subtle variations of natural scents of fig, sandalwood, sea salt, sage, myrrh, and others. Our aromatic notes come from the natural world, which means that the room is just ever so subtly and lightly perfumed. The container may be refilled with your favorite scent.
