PinnacleInsulated Leak Proof Lunch Box for Kids/Adults - Stainless Steel Thermal Bento-Style Container With Additional Tray for Salad/Soup (Navy, 16 oz)

Brought this lunch box ease to open ease to clean good quality.

I’ve tried all of the suggested tricks. This container simply doesn’t keep the food warm. I’ve tried pasta, tacos and chicken tenders for 6 days. My son says his food is cold everyday.

I bought the lunch box for my son to take to school. While it's okay for keeping food warmish, it didn't maintain heat as well as I had hoped. It also has less room inside than expected, which made packing lunches a bit tricky. Overall, it's fine for mildly warm foods, but if you're looking for something that keeps meals hot for longer periods, this might not be the best option.

I buy these for my kids to take lunches to school. They work great, very durable. Says not dishwasher safe but I've always put mine in anyway on the top rack and never had any problems.

It does lock great but it doesn't keep food hot or even really warm. I didn't fill it with boiling water then dry it and then add the food but it didn't even come close to keeping it warm. Also, when you wash it the water gets stuck in the lid. So you have to shake it and leave it upside down and hope the small vending hole helps the water come out.

My daughter brought this to school 2 days in a row. It did not keep her food warm at all and it leaked the 2nd day. The rubber seal would not stay on. Yes we did preheat it with hot water. We returned it in favor of a metal round top thermos.

The food still gets cold in less than an hour. My kid hates cold lunch so when it’s time to eat she won’t bcuz it gets cold fast

It gets pressurized with food inside and cannot be opened.
