When you put ice inside, you can only put so much water in as it’s pretty small. I was expecting it to be bigger as I don’t recall it saying how large it was in the details. It doesn’t keep the ice frozen very long before it melts, that is a disappointment. I bought one for my 7-1/2 year old granddaughter, she will use it in school this year. She will have to refill it with more water as it doesn’t hold that much and the ice will melt making the water not cold. That is a bummer...
