Personally, I either run my nail through the 2 halves on the sides so they come apart. Once you've got a little off, take a pen and stick the point between the casing and the usb part and pry a side apart. Repeat for the other side. Once you've got the whole thing off what I did was break every other tab off so taking it apart is a breeze the next time. I run my flash drive with no casing or anything in school and watch people stare...like how I used Yod'm3D on my school laptop and controlled my friend's laptop using VNC. Haha the teacher watched me mess with Yod'm3D too. Lmao.
