Overview
A school-age child with a packed lunch gets a small stainless steel food jar here. A push button lid opens it with one hand, a foldable spoon comes with it, and the cartoon graphics suit younger kids.
The reason to buy is hot or cold food at lunchtime in a container that fits standard lunch boxes. The limitation is the small volume, which suits a child snack or a modest hot meal.
Who it's for
Parents packing lunches for elementary or middle school children. Adults or teens with larger appetites should choose a bigger jar.
Pros and cons
- Vacuum insulated stainless steel

- Fits standard lunch boxes
- Hold times not listed
- Single design option
Performance notes
A double wall with a vacuum gap slows heat transfer, which is how hot food stays hot and cold food stays cold. Results depend on how well the lid seals and on the starting temperature of the food. Filling with hot food that has been preheated gives better results, though the listing gives no preheating steps.
