Eliminate the opportunity for bartenders, in operations with control systems, to remove the spouts in order to free pour liquor. Heat-shrink the seal over the pourer with a heat gun or hair dryer to secure the spout to the liquor bottle. Heat Shrinks are made of a molded plastic and are packaged 1,000 pieces per carton. Please specify which liquor system these are to be used with when placing your order, so we can provide the correct size.
