The Streamer Liquor Control Pourer keeps track of every drop of alcohol with a pull of the trigger. You can accurately measure 25ml (0.85 oz) or 1 oz. shots, saving you money and preventing waste. The built in numerator registers every shot poured, allowing you to keep better track of your liquor inventory. The base is made from flexible silicone, assuring a perfect seal for all liquor bottles. Every pour on the Streamer is registered on the numerator with or without liquor, and cannot be reset.
