Easy to release: The upgraded large ice cube mold is made of soft and durable silicone material, replacing traditional hard and fragile plastic trays. The elastic raised silicone bottom helps push out ice cubes more easily. Simply press the bottom gently, and the ice cubes will slide out quickly. High-density lid: The lid's edge has been enhanced for a secure fit, ensuring a tight seal. Effectively prevents water overflow and freezing of excess water, while helping to prevent ice from absorbing unwanted odors from the refrigerator. No unpleasant smells after use. Size: 29 x 13 cm, includes 21 ice compartments, forming heart-shaped ice cubes, ideal for chilling whiskey, beverages, fruits, puddings, and more during summer. Stackable design saves space and fits refrigerators of any size. Prevent spills: Each mini cube compartment is separated with a small channel between them. When filling, excess water flows into adjacent compartments instead of spilling over the tray and onto surfaces. Do not overfill beyond the marked groove of each compartment. Food-grade safe material: Made from food-grade silicone, dishwasher safe, non-toxic, odorless, and environmentally friendly. Ensures safety and long-lasting use. Suitable for use with both adult and baby food. Safe for everyday use.
