Frequently Asked Questions
- Can you bring a stainless steel lunchbox or water bottle through airport security?
- Yes. Stainless steel lunchboxes are allowed in both carry-on and checked luggage, as long as they don’t contain prohibited items (like liquids over 3.4 oz / 100ml in carry-on). Water bottles can go through security if they’re empty. Once you’re past the checkpoint, you can refill them at water stations in the airport.
- How to clean bento boxes on the go?
- Most stainless steel bento boxes are dishwasher safe, but when traveling, you can wipe them out with a reusable cloth or rinse with water and mild soap. For odor-free freshness, pack a travel-size bottle of dish soap or biodegradable wipes. Pro tip: keep a silicone collapsible sponge in your toiletry kit—lightweight and perfect for hotel sinks.
- Are these safe for kids and adults?
- Yes. All the products featured here are made from food-grade stainless steel (304 or 18/8) that’s BPA-free, non-toxic, and lead-free. They don’t leach chemicals like plastic containers can, making them safe for everyday use. They’re also more durable—ideal for kids’ school bags, road trips, or outdoor adventures.
- Do stainless steel bento boxes keep food hot or cold?
- Not by themselves—most stainless bento boxes aren’t insulated. To keep food hot or cold, use an insulated lunch bag or add ice packs/hot packs. For drinks, an insulated stainless steel water bottle is your best option.
- What size is best for airplane snacks or day trips?
- For flights, compact boxes under 1.5 lbs (like the Yumbox Prêt or KTKUDY) are easiest to pack. For road trips or picnics, larger 30–33oz boxes (like the AOHEA) give you more flexibility.
