This is a mini spiral notebook. It's rather old, as you can see by the Segasonic name at the cover's edge. This notebook is somewhat unusual as it uses a continuation of the front cover art, for the back. In this case, it's a split image from one of the screens of the old Sonic PC Screensaver. (all the art was done in a single, recognizable style) Which, in this case the scen was Sonic in Space with the space station, Tails and Eggman along for the ride. This was available in the USA as well, as an import in Sanrio stores in 1993.
