A 1050ml vacuum-insulated stainless lunch jar with antibacterial coating, holding hot food at 64°C+ for 6 hours.
About this product
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.
How to use
- Warm the jar with hot water for a minute before adding hot food, then discard the water — this helps it hold heat longer.
- Pack hot food while it's still steaming for the best heat retention.
- Reheat the inner polypropylene container alone in the microwave if needed; never microwave the stainless outer jar.
- Hand-wash the outer body; the inner container and seals can be washed separately, but the set is not dishwasher safe.
Ingredients
- 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.
