Here we have #14, Penthesilea, Mitsuru Kirijo's persona.  Perhaps one of our most favourite names, and a power we would certainly not want to piss off.  A reflective version in the Super Seal series.
 
More information can be found on Penthesilea's Wiki 
 
Persona Super Seals were included in a wide range of Persona 3 physical releases as a fun collectable covering both the major players as well as the shadows they encounter.  We have not tried to stick any of these to anything, but we take their word for it that you can apply these on most any desired surface. 

The descriptions on the back are in Japanese, we hope to have these all translated at a later date and set up on their own menu listing and more detailed trivia on the person or being on the face of the seal.  This series runs up to #83 (more?).
