The Circle Joy CJ-BK03 is a set of four cooling stones designed to chill your favorite beverages without diluting their flavor. Made from food-grade stainless steel, these silver-colored cubes reach a target temperature of 10°C after just 3 minutes in the freezer, ensuring your drink stays cold while remaining undiluted. To make handling easier, the set includes a pair of tongs, allowing you to place the stones into your glass hygienically. These are a practical choice for anyone who enjoys a crisp, cold drink but wants to avoid the watery taste that comes from melting ice.
