Filo d’olio has been designed by Marta Sansoni. “Fior d’olio” is a little iconic mechanical gem for use with “green gold”, another name for olive oil. “Fior d’olio” is a cap with a pouring spout that fits into the neck of the bottle, allowing you to pour only as much as you need on your food, while controlling the oxidation process that begins as soon as the bottle is opened.
