Set of 3 premium 1.5 ounce measured pourers. Includes 1 handy PNW Pocket Corkscrew. HOW TO POUR A MEASURED VOLUME OF LIQUID: 1) Before using the pourer, please soak in luke warm, soapy water for 10 minutes, then rinse in cold water. 2) To install, wet the cork and push the pourer straight into the bottle, making sure the collar fits snuggly over the opening. To remove, twist and pull straight up out of the bottle. 3) Hold the bottle at approximately a 45 degree angle when pouring. Ensure a naturally pouring motion in used; do not "whip" or "baby" the bottle into pouring position. 4) When the bottle is low, allow liquor to reach the neck of the bottle before tilting the 45 degree angle. Bring the spout to the lip of the glass, then raise the tail of the bottle. 5) To wash, soak in lukewarm, soapy water, then rinse in cold water. For best performance with spirits, please wash weekly. When used with cordials, syrups, or juices, wash nightly. 6) If cork fins flattens, run corks under hot water for approximately 30 seconds, then run under cod water. This will straighten the fins. NOTE: Do not run through dishwasher or wash in extremely hot water. Pourers will not be effective with water.
