Stainless Steel Double layer Flask Lunch Box 2.3 Liter

To unlock the full potential of your Stainless Steel Food Flask SUS304, we have a pro tip for you. Before filling it with your favorite meal, add a small amount of hot water to pre-heat, or cold water to pre-cool the flask. This simple step makes a world of difference in keeping your food at the perfect temperature.

• Heat Preservation: By pre-heating, your flask becomes a haven for hot dishes. Imagine savoring a steaming bowl of homemade chili or a comforting bowl of oatmeal, hours after packing them.
• Cold Preservation: Pre-cooling transforms your food flask into a summertime savior. Crisp salads, chilled fruit, or icy yogurt will remain refreshingly cool throughout your day.
• Eco-Friendly and Cost-Effective: Plus, it’s an eco-friendly and cost-effective way to ensure your meals are always at their best.
