Review: perfect little flask - When I ordered the flask I was not 100% convinced that it would work or work well. I have ordered different flasks in the past but they have either leaked or have failed to keep food warm for long enough. The price almost seemed to good to be true as the previous flasks id ordered were more expensive but failed on various levels when trialled. When the flask arrived I had a practise run with it. The flask was for my 7 year old to take to school to use for lunch so on the Sunday before going back to school we had a dummy run with it. This is what we found. 1. The flask was a winner in the colour department. The neoprene cover is great and makes it easy to carry, the clip on the strap is secure enough when carrying but easy enough to unclip to remove the flask. 2. The flask itself is easy enough to open. Its not too wide for small hands, and my wee one was able to open and close it with no issues. 3. The flask doesn't leak. We have tried it with hot water, soup, pasta and rice and all have been safe within the flask. 4. It keeps things warm for hours. During our practise run we filled the flask and checked it 4 hours later. It was still perfectly warm. Each morning I am filling the flask at about 8am. My wee one says that her lunches have been perfect for her to eat when it comes to lunchtime which is usually around 12.15. Overall I am really pleased with this flask. I am actually thinking of ordering one for my older teenager to use for her lunch as the size and appearance would be fine for any age really. I would definitely recommend this flask for kids, if you do buy it have a practice run with your wee one before they use it at school. It really keeps the food warm and is easy to use
Review: Great for children - These are perfect for my children to take hot food to school but I find it doesn’t keep food hot enough for me conspired to thermos flasks I’ve had in the past. With preheating the flasks they keep food warm from 8am until 12.00 . The protective bag works well. Easy to carry and protects against bumps and scratches.

### ⭐⭐⭐⭐⭐ its great for keeping your soup warm
*by K***Y on 6 February 2021*

I got this for my daughter for school, I always put boiling water before i put heated up soup, Its just the right size for a tin of soup, you get a spoon and a cleaner, Its easy to clean out with the sponge which is on long plastic handle, The spoon fits in the pouch next to the container, with the fabric pouch easy to carry, Ive had no problems with it, sonetimes the rubber comes off but i like i can clean it put it back on.
