Keeps ice cold for at least 24 hours in room temperature! Probably longer....just havent tested it longer. The handle and design are perfect. I love that it is light weight, even filled with ice and liquid, so it would be easier to lift, carry and hold for an elderly person.

Best treat ever

My cat is dictating this review to me: These are my favorite treats out of all the things my servant gives me. I've had similar but they're not nearly as good. Inaba really started the entire puree in a squeeze tube market and they're still on top for me. These are especially great when I'm parched since they offer a lot of hydration that dry treats don't. I haven't found a flavor I don't like. Sincerely, Jinx
