Durable, Leakproof, and Perfect for Trips or every day outside the house
This food jar was an absolute lifesaver during my overseas trip! Since I didn’t always have access to a kitchen, I prepared food for two days at a time, and every time we went out I added my baby meal in this jar. It kept everything warm, fresh, and ready to eat. The foldable spoon is sturdy and convenient, though it’s a bit big for my 10-month-old but I carried a smaller spoon in my bag and I also used an extra glass jar to transfer food I will feed her so I didn’t put a used spoon back inside. The seal is amazing—it never leaked, even when tossed around in my bag. The jar is solid, well-made, and strong enough that I didn’t worry about it breaking if it fell. Honestly, the quality matches the price—it’s durable, reliable, and so convenient for travel or everyday use. Highly recommend for parents or anyone needing a dependable food jar! Easy to clean, the lid has a rubber seal easy to remove and instal again.

Great for gifting!
This was great for the price we purchased them as part of a gift bag for our CERT group and included hot chocolate and soup for shelf stable food (that was the theme) they also loved that it came with a spoon and is dishwasher safe for easy cleaning and can be used for hot or cold foods.

Very satisfied with the thermos
I have been using this thermos for more than a year now, and I'm more than satisfied with it. It will keep the food warm for so many hours, and I'm happy since my kid gets to eat a warm lunch daily. I definitely recommend it, and my kid also loves the spoon that comes with it. Very good quality and big enough to keep a hot lunch inside. It doesn't leak and is out every day to go thermos.

Amazing Thermos!
This thermos is perfect for adults & kids lunches!! The double insulated technology keeps food warm for hours. My kids lunches are still warm 3.5 hours later which is perfect for my picky kid who doesn’t like her food cold. It is also leakproof. I can’t tighten the lid super tight because my 7 year old wants to be able to open it herself and it still doesn’t leak. Highly recommend purchasing this item. It also comes with a stainless steel spoon instead of the typical plastic spoon. 10/10 recommend.

Great for school lunch
I bought this for my daughter's lunch for school. The size is great and we love that the spoon is not plastic! It keeps her food warm. The only thing is the color was a bit brighter than expected. Thankfully she was fine with the bright blue.

Well made product
I bought this for my daughter in middle school to avoid school lunch. I love the fact that you can prep the thermos and it will last for hours. We typically use an electric kettle to pour boiling water in it. Once you leave the boiling water in there three or four minutes the metal gets really hot inside. This isn’t an absolute necessity, but it makes the thermos last warmer longer. We warm up our daughter‘s lunch in the morning around 7 AM and by 1 PM it’s still warm for her. This is a great brand and a well-made product. It’s also a very pleasant and neutral color.

This has been delivered in a thin layer of plastic bag, and the cap is dirty as if that’s the last piece in the warehouse (however it’s not because I managed to get a replacement), so be mindful if you want to buy ;) Because my last review doesn’t comply to the community guidelines so my photos are gone. This is also interesting ;)

Perfect size thermos for my 5 year old’s lunch! The thermos heats up well and keeps the food hot for hours. The spoon that was included is a great idea but the connections where it folds can pinch if you’re not careful. Easy to clean and easy to open!
