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!

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.

Keeps Food Truly Hot and Perfect for Packing Kid-Safe Meals
Use: Packing hot meals for outings, school, or events without microwave access This insulated food jar has been a great addition for our family. My son is very picky and has food allergies, so when we go to potlucks or group events I usually bring something I know is safe for him. This container keeps his food hot—and I mean actually hot—until it’s time for him to eat. The 10-ounce size is perfect for kid portions, and the included foldable spoon is convenient so I don’t have to pack extra utensils. It’s easy for him to use and carry, and it feels sturdy enough for regular use. We chose the Minecraft-themed version, which he really enjoys, and it made him more excited about bringing his own meal. It’s especially helpful when we’re not sure there will be a microwave available. Overall, this is a reliable insulated food jar that does exactly what it promises and gives me peace of mind that my child has something safe and warm to eat. Best For: Parents who need a dependable, kid-friendly insulated container for packing hot meals for school, travel, or events without reheating options.

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.

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.

Great for keeping food warm
This one is great. We use it to send hot food with our younger son to school, and it really keeps the food warm for hours. The quality is solid, and it even comes with a spoon, which is super convenient. We’ve also started taking it with us on trips for the whole day. Very happy with it.

This product works perfectly for kids, get it for their lunches and you won't be disappointed. Make sure to condition it with hot water for 10 mins before loading it with food. The included spoon is a huge helper.

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!
