The 8 ounce size is perfect for so many things. They make it easy to bring along a drink, applesauce, yogurt, or other items wherever you go. At the bottom is a zipper type closure which makes refilling them easy, and the top is easy to open and close as well. I haven't had any problem with them leaking, which is definitely a plus too. I love the bright yellow butterfly design and my grandchildren do too.
These are great for the kids, but also work well for me. I can fill one up with applesauce and throw it in the freezer, then use it as an ice pack when packing a lunch for later on. These will also come in handy for taking along on car or canoe trips in the summer.
These are dishwasher safe, although I have only washed them by hand so far since they are easy enough to keep clean. I have been very happy with my purchase and would gladly recommend these to anyone.
