Frequently Asked Questions

Q: How does the thermal insulation work in this stainless steel bento box?

A: This insulated bento box uses a hot-water injection method. Before eating, simply pour hot water into the bottom basin of the box. The heat from the water gently warms the stainless steel tray and its contents above, keeping your food warm for approximately 2 hours. For cold food, use cold water instead. Note that the box itself does not provide long-term passive insulation without water.

Q: Can I put the entire bento box in the microwave?

A: The stainless steel inner tray and lid should never be placed in a microwave or oven. However, the BPA-free plastic (PP) bottom bowl is microwave-safe — just remember to remove the cover before heating.

Q: Is this lunch box suitable for children?

A: Absolutely! The 3-compartment insulated bento box is designed for both kids and adults. Its leak-proof seal ring keeps food securely inside, the BPA-free materials are food-safe, and the separate compartments make it easy to pack a balanced school or outdoor lunch. It also includes a set of tableware for added convenience.

Q: How do I clean this stainless steel bento box?

A: Both the removable stainless steel tray and the BPA-free plastic bottom box are dishwasher safe, making clean-up quick and easy. The smooth inner surfaces also make hand-washing simple. The bottom box is freezer safe as well, giving you even more storage flexibility.
