This is a collection of fun, mini spiral note pads. They look like list pads...possibly for homework or something. Each pad is different. The Sonic one shows him with meteors/space setting, and has stars & SA blue-tone art inside. The Knuckles one has wiggly edges, red coated plastic spiral & blue-tone Knuckles disk shaped art inside, with simple lines for writing. The Amy one is nice & pink, but look at Tails sleeping on his towel in the background. He's emitting/bubbling/snoring hearts out. (The Sonic note didn't have anything interesting on the back, is why it doesn't appear here) 

Photo by SonicTeamThis is a larger version of the notebook seen above. It's pretty much identical to the small one, with meteors, logo & SA1 Sonic. What does it say in Korean in that oval thing? It's cool to see different sizes of useful Sonic supplies.
