Add a pair of pour spouts to your order to help keep your bottles nice and clean. The tapered spout is for oil to help control the flow when being poured. The spout for the vinegar has a wider opening to allow the balsamic to drizzle with ease, since it is thick! We reccomend these as they fit on all of our bottles, and come with a metal flap on them to prevent any debris from getting in them. To keep these clean, soak them in hot water and dish soap, rinse and then they are ready for use again!
