Does a cool-box keep sensitive foods frozen?

Question

If yes, for how long will it stay completely frozen? Can you recommend any particular brand?

Answer 1

There are so  many factors involved, such as the temperature of the surrounding air, and whether the box is packed full.  If the box is full and if the items were solidly frozen, they should be ok for 24 hours if the box is kept in a place that is not too hot.  My daughter-in-law traveled with special ice cream in a cooler, and it was ok overnight, but the air temperature around it was always temperate, never hot.  Wrapping each item separately in newspaper will also help.
