I bought these for my kids to put in there drinks and pack in their lunch box. I wanted to try to keep there drinks cold without watering it down. They didn’t quite last till lunch the first time so I instead put their thermos in the fridge the night before then added the frozen cubes the next morning. This worked much better! Over all they work pretty well and they freeze real fast. #RankBooster #Sponsored #BottledJoy
