Vacuum-Insulated Stainless Steel Lunch Box

This STLB3AG lunch jar pairs a vacuum-insulated stainless outer body with a removable polypropylene inner container, for a 1050ml total capacity split into a 630ml main body and 420ml bowl — enough for around 3 bowls of rice. Silver-ion antibacterial treatment plus a double-wall vacuum structure hold food at 64°C or higher for 6 hours, so rice, curry, or noodles stay warm until lunchtime.

1. Warm the jar with hot water for a minute before adding hot food, then discard the water — this helps it hold heat longer.
2. Pack hot food while it's still steaming for the best heat retention.
3. Reheat the inner polypropylene container alone in the microwave if needed; never microwave the stainless outer jar.
4. Hand-wash the outer body; the inner container and seals can be washed separately, but the set is not dishwasher safe.

• Body and lid — stainless steel with acrylic resin coating.
• Clasps — stainless steel.
• Inner container and inner lid — polypropylene (microwave-safe on its own, separate from the outer jar).
• Seals — silicone rubber; base plate — thermoplastic elastomer.
• Not dishwasher safe.
