Most of the time USB drives aren't all that interesting, but this one is at least, if nothing else, entertaining. It is also highly unlikely that anyone would thieve it from you either.
The USB Drive is from FRED studios and will hold up to 2GB, that is, once it has actually been put on the market. As of now it's not out just yet.
Unfortunately, their site doesn't give any info as to when it will actually be released to be sold online. Likely once it does it will make its way onto Perpetual Kid, since there are plenty of products from FRED studios already sold there.
