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.

Good food jar for school
Very good food jar, keeps my child food warm. Convenient folding utensil inside the cap. Only down side, sometimes get a strong pressure closing and won't open easily (kids proof)

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.

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.
