Great for School Lunches Without a Microwave
Color: Purple Size: 10 Ounce
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. ... show more

Perfect for School Lunches – Keeps Food Hot & Fresh! 🥣💙
Color: Teal Size: 10 Ounce
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! ... show more

A must needed choice for school lunch
Color: Mario Kart Size: 10 Ounce
The thermos keeps food at a good temperature. I like the stainless steel and the insulated keeps the food hot or cold long enough to be enjoyed. The portion size turned out acceptable for lunch meals. Also, an added bonus was the character design which my child loves. Overall, I’m satisfied with this purchase. ... show more

Good for School Lunches, but Not for All-Day Heat Retention
Color: Preschool Minnie Size: 10 Ounce
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. ... show more

Great buy keeps food warm for toddlers
Color: Purple Size: 10 Ounce
My baby loves this thermo. I placed hot cereal in it and it stayed warm for about 2 hrs roughly. I purchased stickers for him to add to it and he enjoyed doing that. It holds enough for an elementary kid. He is full. Washes easy and fits well in his lunch bag. This was an great buy

Game Changer!
Color: Pink Size: 10 Ounce
Bought this for my daughter's lunch. Tested at home first. Put boiling water in the thermos first for about 10 minutes. Air fried some Just Bare breaded chicken breast bites. After 4.5 hours they are still warm. 8 year old approves! I probably would cook them slightly less, because they will cook some in the thermos. They were a little more dry, but still very good! ... show more

For the soup lover
Color: Black Size: 10 Ounce
Great little thermos jar. My kiddo loves ramen and with this, it’s still hot by lunch. It’s probably not necessary to do this but, I will pour hot water into it to warm it up while I cook the ramen. Side note, we also haven’t had any spills or leakage, major bonus.
