This is a ballpoint pen from the drama "Ryusei no Kizuna" starring Kazunari Ninomiya of Arashi. I received it from someone, so I don't know where it was purchased. As shown in the third picture, there is some slight staining on the metal parts. The Ariake 3 mark and the star on the top of the pen move when tilted. I have tested it a little and confirmed that the ink comes out.
