Keep your favorite drinks at your preferred temps with a set of thermal stones. Once frozen, these handy soapstone cubes keep beverages icy cold without the ice (that means no more watered-down sips). Or, pop these versatile stones in the microwave, then plunk them in hot drinks to keep them toasty. With nine stones, you can easily serve a round of chilled-to-perfection cocktails or hot cocoa, making them ideal for entertaining. Crafted from factory excess, these covet-worthy cubes are eco-friendly, too.
