Red Star Rolling Pack Re-Release:
This bag first appeared in 2012, but re-appears in 2016. It has the usual shoulder straps, but unseen (at the back) are little wheels & a pop up handle so you don't have to carry it. On the slanted-shape outer pocket (very glossy) are pointing Sonic & partially faced away peace-sign Tails. He's above a small modern logo, & another one is at the top of the bag. The top is red with an arch of white stars. This has a bigger side pocket with snap top & a water-bottle net pocket on the other side.
Here, it's being sold with the Sonic 'stationary school set' & for some reason, a plush doll. Both of these items demonstrate that the bag isn't very big at all. It's a little-kids size (not standard) pack.
