## Description

From the manufacturer

Review: Must have item! - We are a family of 5 and I have bought several of these thermoses. I couldn’t be without them now. I have tried many alternatives on the market and they do not compare to this one. This one does not leak, it keeps the food very hot (can be extremely hot and kids need to be careful), it’s a great size to pack into lunchboxes or bags and they come in a variety of different designs/colours. They’re great for the kids to take to school so they can have a hot dinner - this is great as mine are fussy eaters and won’t entertain school lunches. We have taken them away on breaks we have had where we go out for long days. And unfortunately our children can be in hospital a lot for various health reasons - these allow me to take them a proper meal when they’re sick of cold food. They can hold a surprising amount of food. More than enough for a little child but also a decent sized adult portion. They are sturdy. They have been dropped several times by kids and they are really tough and can take it. They’re easy to wash - if you’ve had something in it that can leave a residue like curry, just boil some water and let them soak in it with some fairy liquid to get rid of the taste for next time. They are great value for money considering how long they last and how often they’re used in this family. It’s a kitchen staple we couldn’t be without now. I will definitely be repurchasing more in the future.
Review: Good quality and solid - Practical, pretty, loved by my daughter and generally can't be faulted. Many washes later and the seal works great still, the heat is well kept, and hasn't shown any signs of wear and tear. Good product!

## Questions & Answers

**Q: Does anyone else’s flask seem to lose heat through the lid? It seems to get quite warm**
A: Not that I’ve really noticed but you have to make sure the flask is hot inside ( ie boiling water) before you put your food in to ensure it stays hot.

**Q: How tall is this item?**
A: It's about 12 cm tall

**Q: Is this dishwasher safe?**
A: The manufacturer says not to put in the dishwasher. 

I read a review by someone else that said the flask was not retaining its heat as much as it used to and they suggested it was because they had put it in the dishwasher.

 I always do it by hand and it is still working well. The wide neck means it’s easy to get a sponge or brush in there and get all the 90 degree angles (base & shoulders).

DD much happier to take leftovers to school than boring old sandwiches every day.

**Q: Hi there, I purchased this item on the 6th Nov and the seal inside the lid has broken. Is possible to have a replacement part?**
A: No idea try the actual firm via checking on the webb

*by R***T on 24 October 2025*

### ⭐⭐⭐⭐ Great for the kid's lunchbox
*by C***L on 15 October 2013*

I bought this for my 4 year old's school packed lunch, as I wanted him to occasionally have a hot meal at school. I already have a normal size food flask, but I knew this would be to large for him. This flask works perfectly, by the time it is lunch time the food is still hot. My son loves it. Ideal for pasta, rice and noodles, you should ensure there is some liquid, e.g. gravy, when doing these dishes, as the food can be a bit dry. Also ensure the food is piping hot before placing it in the flask, as this will ensure the food stays hot, for longer. My only grievance with this product is the price (I would of given 5 stars, if it was cheaper). Quite expensive for a small flask, especially since I could of bought a larger flask for half the price I paid, but at least it does the job.
