LunchBots 16oz thermos Stainless Steel Wide Mouth - Insulated thermos With Vented Lid - Keeps Food Hot or Cold for Hours - Leak-Proof Portable Thermal Food Jar is Ideal for Soup - 16 ounce - Aqua

Keeps my son's lunch warm from early morning to lunch time at school! Easy to clean and use. Good quality and leak proof.

We’ve tried many lunch boxes before and nothing really worked for my daughter because she prefers warm food. This one has been a total game changer. It actually keeps the food warm for 4–5 hours, which is impressive. My daughter finally finishes her lunch now, no matter what I pack. What I do is simple: I pour warm water into the box for about 10–15 minutes, empty it, and then pack the food. It works perfectly every time. Totally worth buying. If your child likes warm meals, this lunch box is a must-have.

I love this little thermos! It's the perfect size for soup or stew. Easy to clean and easy to use. To make sure it stays warm, I first fill it with hot water and let it sit for five minutes before filling with heated food.

Love how this is easy to use, durable, and gives variety to school lunch instead of just cold or room temperature food. It holds temp well and my daughter is excited to have some warm food just like at home. I’m so glad I bought this.

Good lunch size for hots, decent price, no leaked, nice n shiny, standard lunch room issue

My husband’s office is like the artic for some reason, so he uses this to take lunch. I fill it about 1/3rd full with hot water for about 15-20 minutes (usually while I am cooking) because I read somewhere that this helps an insulated container to keep things warm. It holds about 1cup of cooked rice with about 1 cup of cooked veges and beans. Enough to satisfy the appetite of a 6’1” husband with a metabolism to envy! He normally has lunch about 7 hours after its packed and though it’s been a few years since he’s had it, he still often expresses awe at how warm his food remains, without going bad (though if he leaves it longer, I imagine the heat will make it go bad). He previously tried taking food to work in other insulated containers, with same prep done ahead of packing his lunch, but the food would be, at best, room temperature when he was ready to eat. This one keeps it hot, even though he is in a cold room all morning. Also, so far, no spillages. Really good product!

I had such good results with the 8 ounce containers that I invested in the 16 ounce size also. If I warm these up with boiling water, then pour it out before I put in my lunch, my lunch will stay hot from 5 AM until noon at lunchtime. For years, my husband brought frozen ice cream to work in the 8 ounce size. I would pull the thermos out of the freezer at 5 AM and he would eat ice cream on the train home at 3 PM. I’ve tried other thermos brands and they don’t come close to these. They are worth the investment.

The quality is good.
