Pendrives it's already compatible with: 

-Any Kingston DataTraveler Exodia pendrive.
-For others you must tweak the model a little.

One must simply put the pendrive in its place and fold the cover over i suggest glueing it in place the cover i mean.

It can be used as a gift box for a pendrive which someone would use for storing pictures.
It's also kind of christmas themed. Other versions may be available later.
