Frequently Asked Questions

Q: Is this thermos completely BPA-free?
A: Yes, this thermos container is made from BPA-free materials. The inner lining and all plastic components are free from bisphenol A, ensuring safe storage for hot food, especially for children.

Q: How long does the insulation keep food hot?
A: The double-wall stainless steel construction provides excellent insulation. Under normal conditions, hot food can stay warm for approximately 6-8 hours. For best results, preheat the container by filling it with hot water for a few minutes before adding food.

Q: What are the available capacities and which one should I choose?
A: This thermos is available in 350ml and 500ml sizes. The 350ml is ideal for a child's lunch or a small portion of soup, while the 500ml is suitable for an adult meal or larger portions. Consider your typical serving size when selecting.

Q: Can I use this thermos for cold foods or beverages?
A: Yes, the double-wall insulation is effective for both hot and cold items. It can keep cold foods chilled for several hours. However, it is primarily designed for hot food such as soups, stews, pasta, or rice dishes.

Q: Is the thermos leak-proof and safe to carry in a bag?
A: The lid features a secure screw-top seal that prevents leaks when properly tightened. However, it is not recommended for thin liquids like water or juice as leakage may occur. It is best used for thick or semi-solid foods. Always test by tilting after filling.

Q: How should I clean and maintain this container?
A: Hand wash with warm soapy water and a soft sponge. Avoid using abrasive cleaners or scrubbers that could damage the stainless steel surface. Do not microwave or place in the dishwasher. After washing, allow it to air dry with the lid off to prevent odors.

Q: Is this product suitable for children and what safety features does it have?
A: Yes, it is suitable for older children (age 3+). The BPA-free construction and insulation prevent external surface from becoming too hot to touch. However, the contents remain hot, so supervise children during use. The handle provides a secure grip for small hands.

Q: What is the warranty and return policy for this thermos?
A: We offer a 30-day money-back guarantee and a 12-month warranty against manufacturing defects. If you receive a damaged item or have any quality issues, please contact our customer service for a replacement or refund. Shipping costs for returns are covered by the buyer unless the defect is our fault.

Usage & Care

Before First Use: Wash thoroughly with warm soapy water and rinse. For best thermal performance, preheat with hot water (for hot food) or pre-cool with cold water (for cold food) for a few minutes.

Filling: Fill to capacity for maximum insulation. Avoid overfilling; leave a small gap to allow the lid to seal properly.

Cleaning: Hand wash only using a soft sponge and mild detergent. Do not use abrasive pads or harsh chemicals. Rinse thoroughly and air dry with the lid removed.

Do Not: Microwave, put in dishwasher, freeze, or boil. Do not use for carbonated beverages or dry ice.

Caution: Contents remain hot for hours. Always check temperature before serving, especially to children. The outer surface may become warm over long durations but remains safe to handle. Use the handle for secure grip.

Storage: Store with lid off to prevent odors. Keep in a cool, dry place when not in use.
