Your standard USB 2.0 flash storage, but with a cute design on top. Kind of overpriced for what it is considering you can get them with no design and twice the GBs for even cheaper, but it's pretty cute.
These are super cute and are worth the money. They are really reliable and are fun to carry around instead of just a plain USB. They make using a USB more enjoyable because they are not what you usually think of when you think of a USB.
