I think the cooling time will be about 18 hours. After receiving it yesterday, I put 2 ice packs in it and checked it, but 1 is fully recorded, 1 is 90% recorded.

Nature Hike Icebox..I understand that shipping took a long time. However, it is difficult to understand why the space between the lid and the body is made like the picture. In an ice box that already needs to be sealed. It seems that there is a loss in cooling maintenance thanks to this.

It seems difficult to move because there are no wheels, but it is sturdy.
