The Scent Scene™ Duo includes the bespoke gold metal vessel and two individually packaged Scent Stems™ fragrances: Kyoto in Bloom Camellia & Lotus and Lost in Amalfi Sea Mist. To use place your Scent Stems™ of choice into the metal vessel, ensuring it's placed on a flat surface away from open windows or vents. After 30 days, or a time of your choosing, swap out the Scent Stems™ for the other supplied fragrance.
