preheat it with hot water for the best results
The THERMOS FUNTAINER has been really great for packing kids’ lunches. It keeps food warm for hours, so things like mac and cheese, soup, or chicken nuggets are still warm by lunchtime. The 10 oz size is perfect for kids—not too big or too small—and I love that it comes with a spoon that stays attached, making it super convenient. It feels durable and holds up well to everyday use, plus it’s easy to clean. The only thing is you’ll want to preheat it with hot water for the best results, but overall it’s a solid lunch container for school or outings.

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!

A great thermos for school lunches
This is a great little thermos that has proven itself useful for my kid's school lunches (so much, that I have bought one for each child.) Every Thursday my kids are unhappy with the school lunch options and only request SPAGHETTI AND MEATBALLS. So, every Thursday I get up a few minutes earlier to prepare the lunch for my tiny tyrants. I can't imagine eating cold meatballs...so that is where this thermos has saved the day. Every Thursday. This thermos does what is should and is super effective at keeping hot foods hot. I have found the key to keeping everything hot is preheating the thermos by filling it with boiling water and letting it sit for five minutes or ten minutes to capture the heat before dumping the water out and adding the food. That way the metal doesn't seep the heat from the food. This little step makes all the difference! When lunchtime rolls around, my kids are thrilled to dig into their perfectly heated pasta. However, while the thermos keeps their meals warm for hours, I have noticed that the lid can be a bit tough for little hands to unscrew. Just a tip: be careful not to over-tighten it! With a gentle hand, my kids can manage it just fine. (Or ask a teacher or strong friend for help.) The spoon is a clever idea, but I hate seeing white plastic dirty (I feel like I can never get it properly clean and it is always stained with spaghetti sauce) so I typically just throw in a spoon/fork from home and hope they don't use the white one that comes with. But if they do, no worries. Overall, this thermos is a fantastic investment for families who want to serve a hot lunch...a few hours later. Five stars for its excellent heat retention and the joy it brings to my kids on Thursdays around noon

Good for School Lunches, but Not for All-Day Heat Retention
This is a good and practical container for my child's school lunch. It is easy to use, the folding spoon is convenient, and the size is perfect for packing warm meals. However, in my experience, it does not keep food hot for 8 hours, and definitely not 24 hours. It keeps food warm well for about 4 to 5 hours, which is enough for a school lunch but not for all-day use. Overall, it is a quality product and works well for its intended purpose, but the heat retention claims seem a bit optimistic.

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.
