Stainless Steel Lunch Box with Heat Safe Silicone Insert
This dual-material lunch box combines 304/18-8 stainless steel construction with a premium food-grade silicone compartment for maximum versatility. The removable silicone insert transitions seamlessly from freezer to microwave to oven, while the stainless steel base provides durability and oven-safe functionality up to 450°F.
The leak-proof design features soft-touch silicone clips in blue abyss for secure closure and easy opening. At 7.5 x 4.75 x 2.25 inches, this lunch box offers practical capacity for meal prep, work lunches, and food storage without taking up excessive space.
Key Features
The silicone insert handles extreme temperatures from -40°F in the freezer to 450°F in the oven or microwave. The stainless steel base is oven-safe but must not be microwaved. Both components are dishwasher safe for easy cleanup. LFGB/FDA certified materials ensure food safety, with no BPA, PVC, phthalates, or latex.
The leak-proof seal keeps liquids contained during transport when properly closed. The silicone gasket on the lid creates a secure barrier when the clips are fastened correctly. This makes the lunch box suitable for soups, sauces, and other liquid-containing meals.
Usage Guidelines
Wash and dry all components before first use. For proper sealing, ensure the top edges of the base and silicone seal are clean and dry. Press the lid down firmly on all sides before closing the clips. Leave at least 1.5 cm of space at the top to prevent overflow. Keep the box flat during transport when possible.
The stainless steel components are oven-safe but not microwave-safe. Remove metal parts before microwaving the silicone insert. Both the box and insert work for freezer storage at temperatures as low as -40°F. Avoid bleach, chlorine-based cleaners, and abrasive scrubbers to maintain the finish.
