This is a stylus pen for iPad. Removing the cap reveals a stylus on one end and a ballpoint pen on the other. The retail price was around 4000 yen. The stylus pen is only compatible with older iPads. The ballpoint pen is out of ink (it can be used if the ink is replaced). Therefore, I am selling it as a junk item. The stylus pen still responds on recent iPads, so it can be used like your fingertip.
