Review on Plastic Reusable Pouches Concealable Drinking by Cody Wuol

I don't know how all those who said they put smoothies in theirs did it - the funnel is about 2-3 toothpicks wide so there was a huge mess with the fruit smoothie. If you're just using liquid, great. Shake - no. I was going to freeze them and reuse them because there's a lot of plastic in them, but I'm sending them back :(
