Innobaby's Keepin' Fresh Stainless Steel Lunchbox is a SMART food storage solution for home and on-the-go. Great for storing sandwiches, pastas, veggies and more. The double lined wall keeps food cold or warm up to 2 times longer than standard containers while acting as a protective shell to protect little hands from extreme temperatures. The airtight hinged lid is a snap to open and close, seals in freshness, and is simple enough for toddlers and small children to use. The perfectly portioned stainless steel bentos are easy-to-wash too, thanks to the removable stainless insert. Top rack dishwasher safe. Innobaby's Keepin' Fresh Bentos are also freezer safe, BPA free, phthalate free, PVC free, and lead free.
