Using a patented valve, this 8.6-cm- long atomiser pumps perfume out of the original fragrance bottle into its vial, with a display indicating the fill level. The atomiser is crafted from high-tech aluminium, the same material used in modern aircraft, making it highly robust, lightweight, and 98-percent recyclable. Thanks to a pressure-regulating system, the Travalo Excel travels safely on planes in the passenger’s carry-on luggage.
