Frequently Asked Questions

Q: How long does the insulated lunch box keep food warm or cold?

A: At room temperature, the triple-layer insulated lunch box is designed to keep food warm or cold for up to 3 hours. For best results, pre-warm the containers with hot water (or pre-chill with cold water) before adding your food.

Q: Are the stainless steel containers safe for microwaving?

A: The containers are made from food-grade 304 stainless steel on the inside. Please remove the stainless steel container from the outer PP casing and lid before microwaving. Always refer to individual component guidelines for microwave use.

Q: Are the lids truly leakproof for soups and sauces?

A: Yes! Each lid features a built-in silicone sealing ring that creates an airtight, leakproof seal, preventing sauces and soups from leaking. The exhaust valve on top also releases air pressure so the lid opens easily after sealing.

Q: Is this lunch box set suitable for kids?

A: Absolutely. The set is designed for both adults and kids. The containers are made with FCM-certified, food-safe materials with no high-concern chemicals, making them a safe and eco-friendly choice for the whole family.

Q: Can I use this set for meal prep?

A: Yes! The three separate stackable containers are perfect for portion control and meal prep. Pack different foods — like a main dish, side salad, and snack — without worrying about flavors mixing, thanks to individual lids and sealing rings.
