Set of one dozen Sure Shot Precision Pour 1-1/2 ounce portion pourers With Fliptop Seal. Precision Pour fliptop seal spouts protect your liquor inventory against fruit flies and contaminants. When your bottles are upright, the closed fliptop prevents anything from entering the bottle. When the bottle is tilted into a pouring position, the hinged fliptop opens smoothly allowing liquor to pass through the spout! Patented 3 ball bearing, blue pourer from Precisioun Pours, the best pourer of its type available. Design was based on our over fifty years experience in the bar and restaurant industry. Never overpoured or underpoured, just the same good drink every time.
