I washed it with the intention of using it, but it's bigger than I expected, so it's unused. Therefore, I'm selling it at a low price. The bottom is narrow, so it can be stored in a car, etc. *Actual product photos available *I use a size smaller than this product, but the cooling/heating time varies depending on the indoor temperature. I think the ice will melt in about 4-5 hours in warm outdoor air.
