Precision Pour Measured Pourers w/ FLAP For LARGE BOTTLES, 1-1/4 Oz "" #1 Selling Brand- 3 Per Pack, Made entirely in the USA Heavy cork spouts fit most 1.75 liter bottles and brands such as Patron, Cuervo 1800 and Cabo Wabo. Fliptop seal spouts are similar to our other fliptop seal style spouts in that they protect your liquor inventory against fruit flies and contaminants. By reducing overpouring and spills with Precision Pour spouts you can serve an additional two to four drinks per bottle. This means that a Precision Pour spout will pay for itself in just one bottle. Three ball bearings, rather than the old standard two, for a smoother, more accurate pour. A new bottom design that ensures that the ball bearings will never fall into the bottle. Precision Pour spouts are made using virgin plastic, a far more durable material. Some old-style spouts also employ polycarbonate plastic which will break down in alcohol. We use no poly-carbonates.
