Kauai Coffee Stainless Steel Mug & Straw - Jason Kuehu Tribal Design

I poured the last of my cold soda into the and took it with me in the car to run some errands. After getting back home keeping groceries and finishing my chores. I needed a cold refreshing drink. I remembered that I poured the last of my soda into into my mug. I went back out to my car to retrieve my cold soda in the mug. After 3-1/2 hours I was expecting to pour out the warm soda, but to my surprise. My soda was still cold. It sure was nice to have a cold drink since I didn't have any cold soda left at home.
