2pk Silicone Ice Tray is designed with an ice stick shape that fits most water bottles. Ordinary ice cubes often cannot fit through the narrow openings of many water bottles, but these slim ice sticks can easily be inserted into sports bottles and drinkware to keep beverages chilled for longer. Whether you're at the gym, outdoors, or on the go, enjoy cold water whenever you want. After freezing, simply let the tray sit at room temperature for a few minutes and the ice releases effortlessly. Made from food-grade silicone, this ice tray is soft, durable, and safe for use with drinks and food. It is freezer, oven, microwave, refrigerator, and dishwasher safe, making it convenient for everyday use and easy to clean. This versatile silicone mold can be used not only for making ice sticks but also for preparing various treats such as candy, chocolates, cakes, bread, mousse, jelly, pudding, and more. Create fun snacks for kids and pets with ease.
