This is a thin, mini note pad that's likely to be a promo-give-away type item. Likely promotional because it's advertising oriented, showing you Megadrive pictures, Sonic 1 screen shot, claw machine/UFO & the prize plushes you can win in it.

Buyable items don't tend to be quite so merch-promoting. The front of the pad has finger-waving Sonic looking like the game's title screen complete with banner & star ring. The bakc has the plushes, screencap, "looking out" stock Sonic, & UFO machine with some info (but it's all in Japanese) The inner cover has blue/white (like black and white photo but with blue) of the plushes again so you can see them closer. Each page of the note pad also has a 'watermark' type Sonic graphic. With Sonic pictures & theme all over, this is a quality pad for such a promo item!
