Perfect for School Lunches
This food jar is the perfect size for my 5-year-old. It comfortably fits about 8–9 nuggets or other small meals, and it keeps the food warm until lunchtime. The design is cute, and the foldable spoon is a nice bonus. Very happy with this purchase!

Good item for younger kids
It’s a small thermos but my son loves it when I pack rice for lunch and since he’s in Kindergarten, it’s compact and small. Comes with a plastic spoon, food stays warm for 5 hours.

Practical, Durable Thermos That Keeps My Kid’s Lunch Just Right
After going through three disappointing kids’ thermoses, I finally found this gem that my 7-year-old has been using for the past 4 months of school lunches.The standout features:- Genuinely keeps food warm for 5+ hours (tested with soup, pasta, and mac & cheese)- Kid-friendly lid that my child can open independently- Wide mouth makes it easy to eat directly from the container- Exterior stays cool to touch even with hot contents- Perfect 10oz size for elementary school portions- Fits perfectly in standard lunch boxesDurability has been impressive. Despite being dropped multiple times (as kids inevitably do), there are only minor scuffs on the exterior. The seal remains tight with no leaks, and the hinge on the lid shows no signs of weakening.Real-world testing: I’ve sent hot pasta at 7:30am, and my daughter confirms it’s still warm at lunchtime (12:15pm). For cold foods like yogurt or fruit, it maintains temperature equally well. No more complaints about “gross warm yogurt”!Cleaning is straightforward – all parts are dishwasher safe, though I typically hand wash to preserve the seal. The wide mouth means no awkward angles that trap food.Minor cons to consider:- Slightly heavier than plastic alternatives (though this contributes to its insulating properties)- The colored exterior can scratch to reveal the steel underneath- The rubber seal needs occasional deep cleaning to prevent odorsOne helpful tip: pre-warming the thermos with hot water for 5 minutes before filling significantly extends the heat retention.Bottom line: A reliable, practical thermos that actually performs as advertised. After multiple disappointing purchases, this one finally meets a parent’s expectations for durability and a child’s requirements for usability.Perfect for school lunches, day trips, and sports events when you want your child to have a proper warm meal without access to a microwave.

Great for School Lunches Without a Microwave
1. First ImpressionsWe got this Thermos Funtainer for our child’s school lunches since there’s no access to a microwave, and it’s been a lifesaver. The size is perfect for a single portion, and the purple color is fun and kid-friendly.2. Product PerformanceThis jar does exactly what it promises—it keeps food warm from early in the morning until lunchtime. I prep it around 7 AM and when my child eats around 12 PM, the food is still hot. A tip that’s really helped: fill it with hot water for a few minutes before adding the food, then empty and add the meal. It really improves heat retention. The included foldable spoon is a great bonus and fits right into the lid.3. ProsKeeps food warm for 5+ hoursCompact and fits easily in lunch bagsBuilt-in foldable spoon is super convenientEasy to clean and kid-friendly design4. ConsNone so far. Just be sure to pre-warm it for best results.5. Final ThoughtsIf your child’s school doesn’t allow microwave access, this is a must-have. It’s durable, functional, and makes it easy to send hot meals from home without worry. Highly recommend for soups, pasta, mac and cheese, or even chicken and rice.

Excellent quality and ease of use
Purchased this for my grandson’s lunchbox over the summer. He could hardly wait for school to start to start using it. His mom verifies the ease of use and temperature retention. Grandson loves the minecraft pattern, and grandma likes that we have one less thing to worry about. I have complete confidence in this product!

Passou no teste! Coloquei água quente as 14h e as 19h ainda estava quente! Não descartei a água e deixei até as 23h, a água permaneceu quente, tinha perdido um pouco da temperatura mas ainda estava bem quente. E NÃO VAZOU NADA!!!O ponto negativo é a tampa, se você apertar muito cria um vácuo e fica muuuuito difícil pra abrir! O ideal é deixar a fechadura alinhada ao nome da marca impresso no pote. Mesmo que você fique tentado a apertar mais, com medo de vazar, não aperte! Não vaza fechando dessa forma e não fica difícil de abrir!
