This set contains two pieces of 4-cavity large square ice cube molds crafted from 100% food-grade silicone material, which is completely odorless, non-toxic and safe for direct contact with drinking water, fruit, wine and other edible ingredients. The silicone body features soft yet resilient texture, allowing users to twist and squeeze the mold gently to fully release intact big square ice cubes without cracking or residue sticking to the cavity. Each mold has four independent 5cm square compartments, producing oversized ice cubes that melt slowly to avoid diluting the flavor of whiskey, bourbon, cocktail and other craft drinks. A transparent sealed plastic lid comes matched with every ice tray, effectively blocking dust, food odor and water overflow during freezing; the stacking design allows multiple molds to be layered neatly inside refrigerators to save storage space. A small side handle is integrated on each mold for convenient lifting and moving without slipping, while the overall dimension of each tray is 12.7×11.5×5.6cm with a lightweight 111g weight for easy daily operation. The product supports simple DIY production: users can add fruits, herbs or edible flowers into cavities, pour liquid in, cover with the lid and place it in the refrigerator to freeze. The silicone ice mold is fully dishwasher safe, which can be directly put into dishwashing equipment for quick cleaning after use, and it resists high and low temperatures without deformation or fading after long-term repeated use. This multi-functional ice making accessory fits household kitchens, home bars, party scenes and outdoor gatherings, ideal for making ice for spirits, juice, soda and cold brew coffee. Every detail is optimized for daily family use, from leak-proof lids to easy-release flexible silicone, bringing simple and efficient large ice cube making experience for all cold drink lovers.
