Garnish your drink with something classic with the help of Tovolo Stacked Rocks Ice Molds. Recreating the look of rocks stacked in a glass, this single ice cube will melt slowly, ensuring every drop of your drink is cool without over-dilution. The easy-to-use molds feature a stable plastic base and a leak-free silicone lid. Simply fill the plastic base to the fill line, then gently insert the silicone lid to create a seal. A hole in the top of the lid allows air to escape as the water freezes, creating seamless rocks. The stackable molds save space in the freezer, and the stable base and leak-proof lid will keep the water inside the mold.The classic stacked rocks design adds sophistication and class to every drink. Add to whiskey, bourbon, cold brew coffee, cocktails, mocktails, ice tea, and more. Easy-to-use ice molds make it easy to elevate every drink you make.
