To say I love my Northern Lights Frost Buddy To-Go Buddy would be an understatement! This thing is amazing and I don't know what I ever did before I knew about and purchased a To-Go Buddy. They are so versatile... you can use them for cold to-go drinks, hot to-go drinks, and as a tumbler for any kind of beverage you like. The Northern Lights specifically is so beautiful because in the light it has both purple and green sparkles! This is a small family own company that is truly customer oriented and you can really feel it in their actions not just their words. I definitely recommend!
