The European style of free-flow spirit pouring can get rather expensive. Put a limit on the amount you serve with the automatic measured pourer from Suprobarware. Just like the name suggests, it pours an exact 30 milliliter measure of spirit straight into your glass making it ideal for parties and events.Measured Pourer Operating Instructions:· Simply attach the Exacto Pourer to your bottle· Make sure you turn the bottle to a high angle when pouring· The ball-bearing system inside the Exacto Pourer follows the flow of the liquid and plugs up the spout ensuring you get the right amount· To dispense another measure you must turn the bottle upright again; the ball-bearing will then return to it's original position, ready for the next measurePlease Note:If you find the ball-bearing system is not working properly, please ensure you are holding the bottle at a suitable angle. If you hold the bottle at a too horizontal angle the ball-bearing will not flow very easily, if at all.Product Features:· Plastic construction with ball bearing mechanism· Pours an approximate 30ml shot· Allows you to quickly and easily pour shots· Reduce WastePacks Available:4 x PourersQ&A:Q:Why is this pourer inaccurate?A:An air-tight seal must be created and tested with alcohol,wine and spirits only.The first test is generally inaccurate in order to exhaust air, and it will start to be accurate the second or third time with the correct method.Q:Is it difficult to pull out of the bottle?A:Don't pull it out to hard, just put your thumbs on the edge of the black collar and gently push it out. Pulling too hard could damage the joined part of the pourer.
