How to Choose a Lunch Box
From leakproof stainless steel bento to space-saving collapsible boxes and hot-keeping lunch jars, here’s how to pick the right lunch box for work, school or days out.
1. By material
- Stainless steel — durable, hygienic and keeps food fresh; great for bento-style meals.
- Collapsible silicone — folds flat to save bag space when empty.
- Ceramic — microwave-friendly and easy to clean for home or office reheating.
- Insulated lunch jars — keep soups, rice and drinks hot or cold for hours.
2. Leakproof & compartments
Look for a secure, leakproof lid if you carry sauces or curries, and multiple compartments to keep foods separate — ideal for balanced bento lunches.
3. Size & portability
Choose a capacity (in ml) to match your appetite — compact 200–400ml boxes for snacks, 600–1000ml+ for a full meal. Pair with an insulated bag to keep everything neat and at temperature.
