Q: How long does the vacuum insulation keep food hot or cold?

A: No, the vacuum insulated lunch box is not microwave-safe because the stainless steel construction can damage the microwave. For cleaning, we recommend hand washing with mild detergent to preserve the vacuum seal. The foldable spoon is dishwasher-safe for convenience.

Q: What is the foldable spoon made of and how does it work?

A: The foldable spoon is made of high-quality stainless steel for the head and food-grade plastic for the handle. It folds into a compact size to fit inside the lid or a separate compartment for easy portability. When unfolded, it provides a standard spoon length for comfortable eating.

Q: What is the warranty on this lunch box?

A: We offer a 1-year warranty against manufacturing defects, such as vacuum insulation failure or lid sealing issues. Normal wear and tear, including scratches or dents from regular use, are not covered. Please retain your purchase receipt for any warranty claims.
