This book bag is likely the 'match' for the "Big CG Ring" lunch carrier. It has the large CG ring again for the large square outer pocket that also has CG Sonic, Tails & Knuckles jumping up. The top outer pocket (arch shaped) is of interest though, since they've added both Shadow & Dr Eggman to it, along with the logo. The sides of the bag are black, with "Sonic" spelled out in a blocky font in sprays of blue 'airbrush' tone. This has the usual shoulder straps, is about 16 inches (fairly standard kids size) & does have a waterbottle & zip side pocket. This bag should also be in the Gear School Store.
