Silicone Prep-N-Freeze Portion Tray is perfect for preparing and freezing all kinds of foods in advance for fast and easy future use. Made from LFGB silicone with a BPA-free polypropylene lid, the tray measures 12 x 5.25 x 2-inches and collapses down to 1-inch for easy, compact storage. Its sturdy base stands on its own, yet flexes enough to unmold foods easily with just a gentle twist. Each of the 4 sections include a 6-ounce fill line, making food preparation for family meals and entertaining guests super simple. Ideal for homemade soups, stocks, smoothies, sauces, gravies, and more, it's microwave safe for easy portion defrosts and heatups. HIC Kitchen's Silicone Prep-N-Freeze is shatterproof, temperature safe (from -40 to 482-degrees Fahrenheit lid not oven safe), and dishwasher safe for easy cleanup.
