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!

Perfect for School Lunches – Keeps Food Hot & Fresh! 🥣💙
The THERMOS FUNTAINER 10 oz Food Jar in Teal has been a total win for packing kids’ lunches. It’s the perfect size for soups, pasta, oatmeal, or snacks, and it keeps food at the right temperature for hours. The insulation is excellent—hot foods stay warm until lunchtime, and cold items stay fresh without any leaks or sweating. The lid seals tightly, so I never have to worry about spills in a backpack, which is a huge relief. I also love the included spoon—it stores neatly inside and makes it super convenient for kids to use at school without needing extra utensils. The wide opening makes it easy to fill, eat from, and clean afterward. The build quality feels very durable, and it’s clearly designed to handle daily use by kids without any issues. Plus, the teal color is fun and vibrant, which makes it a favorite. If you’re looking for a reliable, leak-proof food jar for school or travel, this one is a fantastic choice. Highly recommend!

Great quality
Purchased for my daughter to use for her school lunches. This has been very helpful for taking hot and cold foods. Keeps food warm and or cold until her lunch time, which is about four hours. The quality looks great and it comes with a folding spork which is very handy. Washes easily hand wash or in dishwasher.

Kids lunch game changer
I got this insulated thermos for my kids’ lunches and it’s been a game changer. It keeps foods like mac and cheese, soup, and pasta warm until lunchtime, which makes packing hot meals so much easier. The size is perfect for kids, and it’s durable enough to toss in a lunch bag without worrying about leaks. I also like that it’s easy to clean. Overall, a great option for keeping lunches warm and making sure my kids actually enjoy their meals at school.

Holds temperature great, a little difficult to clean.
I work 12hr shifts in a hospital and typically don’t break out my lunch till 7-8 hours after it’s been packed. This keeps everything cold or hot BEAUTIFULLY. It’s practically the same temperature I put in it when I finally crack it open. The spoon in the top is really nice since I don’t have to pack a “lunch utensil” set and it folds up nicely. There’s a rubber gasket in the lid to stop liquid from leaking. So it is leakproof. I can confidently chuck this in my backpack and never worry about it. However the gasket has to come off to be cleaned right so it can be kinda difficult. The whole thing is super sturdy, but the hinge the spoon compartment is plastic and could break easy if you aren’t too careful with it. It’s easy to open and the wide mouth makes it easy to pack. I bought two of these for yogurt and overnight oats, I just wish the gasket was a bit easier to remove and clean, it’s really thin and small and I’m always afraid of ripping it.

¿Qué tal estuvo el producto? THERMOS FUNTAINER
A very good thermos—it delivers on its promises. My son is very happy with it; he gets to eat a hot lunch every day. And what makes it even more fabulous is that it features his favorite cartoons from *Patrow*.

Great for School Lunches Without a Microwave
1. First Impressions We 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 Performance This 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. Pros Keeps food warm for 5+ hours Compact and fits easily in lunch bags Built-in foldable spoon is super convenient Easy to clean and kid-friendly design 4. Cons None so far. Just be sure to pre-warm it for best results. 5. Final Thoughts If 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.

Aparentemente bom
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!

KEEPS FOOD HOT
I didn't want to write a review immediately, as I wanted to know if this is a good product. Had seen review videos before buying this brand. Honestly, it did not disappoint me. The food stays hot for hours together, rice , pasta, dal, etc. I preheat it by adding hot water and closing the lid for 10 minutes. It is leak proof, has a small foldable spoon, good packaging, not rusting. Looking for good lunch box then this is the Best Choice . My daughter's friends were amazed to see hot food even after so many hours and they were also keen on buying the same.
