Right size, keeps things nice and cold

The perfect size. I bought two: one for home and one for work and they do a great job of keeping my ice water nice and cold. If there's any negative feedback it would be that there are too few color options. It's black and gray (the colors I purchased) and then 2 or 3 pastels. Offer a Navy Blue and a Kelly Green and a Red.

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
