DD 7, DS 4 and I had a few magic bandits. I am the backpack carrier in our family, and I lost all of mine (and eventually my magic band too). The kids, especially DD7, managed to hang on too theirs, for the most part. They were only $7 for the package, so I didn't worry over the lost ones. They pop into the unused holes used to secure your band, so the posts are very small. They would not fit in crocs.
