Food-Grade Silicone, Safe & Healthy: Made of food-grade silicone. Unlike rigid plastic trays, it won't absorb odors or stains, keeping your food and ice cubes fresh and odor-free. Withstands extreme temperatures (-40°F to 446°F), allowing direct transfer from freezer to oven or hot water. Leak-Proof Lid Design: Features an exclusive, good quality PP lid that resists bending to prevent spills, cracked in the freezer, and cross-odor. Stackable design maximizes freezer space efficiency. Perfect Portions, Efficient Meal Prep: Three convenient sizes (½ cup, 1 cup, 2 cup) offer ideal capacities for single servings of soup, sauce, or stew. Prepare broths or food puree in batches, freeze in portions, and use anytime—saving both time and freezer space. Ultra-Flexible, Easy to Release: The highly flexible silicone allows frozen blocks to pop out effortlessly with a simple push and twist—no forceful tapping or risk of damaging the mold. Cleaning & Care: The smooth, non-stick surface cleans easily. All parts (mold + lid) are top-rack dishwasher safe, convenient and efficient Beyond "Soup", Multi-Purpose Use: More than just a soup cube tray! Perfect for making coffee ice cubes, sauce portions, smoothie blocks, hotpot broth, and even small desserts (e.g., jelly, pudding). - A1
