Scented Oil Diffuser. Clay Pebble Diameter: 5 cm To add a fragrant touch to your small spaces, we offer you a perfume diffuser. Versatile and easy to use, you can place it anywhere. With a few drops of perfume extract, the pebbles scent closets, the car, laundry, or even a handbag. To refresh, put 3 or 4 drops of perfume or essential oil on the clay pebble and renew every 3 days. The pebble is handmade in France. Each pebble is randomly marbled, making each piece unique! The diffuser will resemble the image, but cannot be identical as we choose it randomly from all the pebbles, so we cannot guarantee a specific color and marbling. Each pebble comes in a pretty organza pouch. It is an ideal oil diffuser for small spaces, the bedroom, the car, or a travel bag. The pebbles are delivered without fragrance. Unscented.
