Perfect for kindergarten school lunch
My son LOVES Lightning McQueen, so we grab anything with him on it. 🚗💨This thermos is PERFECT for warm school lunches! I’ve been using it every single day for 2 months, and it still looks brand new — no scratches, no dishwasher marks. My 5-year-old opens and closes it all by himself. Portion size? Spot on for a 5-year-old.It doesn’t keep food hot for super long — after 3 hours it’s just barely warm — but honestly, that’s kind of a bonus so he doesn’t burn himself. Lightweight, super easy to open, and the spoon is fantastic. If it came with a fork too, I’d give it 6 stars! ⭐⭐⭐⭐⭐Big thanks to the maker and seller for such a fun, high-quality product!

Best soup thermos that keeps food warm for hours!
These thermos are perfect for kids! I have two kids in elementary school and they’re able to open and close these on their own. It also comes with a foldable spoon under the lid. I like packing soups in here–I just warm it up in the morning, put it in the thermos, and my kids get a warm lunch a few hours later. It’s really easy to clean and the nonslip grip at the bottom is a plus. It’s important to note that this is stainless steel and non toxic.

Good product
Pros: sturdy, safe, durable ,well insulated and keeps food warm for 3-4 hours , available in variety of colors, small spoon attached .Cons : could be hard to open for younger kids if closed too tight. Food does accumulate on the inner rim of the lid but can be cleaned by soaking in soap for an hour to sanitize.Overall very pleased with the purchase and will buy again.

Great Thermos
We use this thermos for my son’s school lunch several times per week. It keeps his food warm, he can open it, and I love that it has a spoon. It’s the perfect size for a lunch box.

Stays Hot, Stays Cold, Stays in One Piece (Mostly)
Lunchbox lifesaver! Keeps soup hot and yogurt cold until lunchtime, fits perfectly in kids’ lunch boxes, and is super easy to clean. Lid still pops and seals great after a year. Only flaw? The little folding spoon broke fast—but not a dealbreaker since we use our own. Cute colors, tough enough to survive drops, and kid-approved!

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 design and durability
Fantastic product. It keeps food hot or cold for hours, and the metallic exterior looks sleek and modern. It’s durable, even after many dishwasher cycles, and the included folding spoon is a great bonus that keeps my regular spoons from disappearing. Excellent quality and value.

Perfect for lunches on the go
This thermos is fantastic for work lunches. Holds a little over 10oz of liquid. Great for soups or sauces. Keeps contents hot for a good 6 hours. The quality is great for a Thermos brand!

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!
