Our bestselling Stone Drink Dispenser is sure to be a hit at any party or event. Serve your drinks on the rocks! (Or through one!) Available in 4 different granite colors which makes it easy to match with your counter-top, bar or home décor. Fabricated from New England quarried granite and a valve topped with a natural stone handle. Optional Valve Materials: Chrome Plated Brass Valve or 304 Stainless Steel Valve (Prop. 65 compliant - required in CA and with online retailers). To use: Simply place the stone on top of the opened bottle, then turn them back over together as one. Instructions included. For your customer that finds the original method of loading the dispenser difficult because of the combined weight, we offer a handy accessory called the “I Ain’t Lifting That Rock!” Stone Bottle topper. US Patent #9,016,525 Stones vary in shape, size, color, texture, weight and may or may not have natural mineral deposits.
