Prepare portioned meals with ease: Each compartment of the silicone freezer tray has clear 1/2-cup/1-cup fill lines (125ml/250ml), perfect for frozen soups, stews, lasagna, leftovers, and more. Preparing weekly meals or pet food portions becomes much easier. Safe and durable: Made from platinum silicone, these freezer trays are reinforced with built-in stainless steel, making them both flexible and strong. They can withstand long-term storage at low temperatures without breaking, are oven and dishwasher safe, and are an ideal alternative to plastic containers and disposable bags. Superior sealing and leak-proof design: Each compartment comes with a transparent sealing lid that ensures a good seal in each compartment, effectively locking in food freshness and preventing leaks. The transparent design allows you to quickly identify the food inside without opening the lid. Easy to demold and clean: The non-stick, smooth silicone surface prevents food buildup and makes cleaning easy – quick hand wash or dishwasher safe. Space-saving and versatile: These sturdy trays are designed to stack neatly to form perfect squares, maximizing freezer space and keeping frozen food organized. In addition to soups and leftovers, they can also be used to freeze stews, juices, desserts, and even large ice blocks for use in the freezer.
