This is another "5 Item School Set" where it kiiiind of is.
It's called the "Gotta Go Fast! Backpack Set". The backpack brings in a new element, which is a shiny silver crackle-finish foil. It looks nice, and is under a clear plastic so it will probably stand up to wear. The backpack background is mostly abstract/lines & has pointing CG Sonic large on the bottom. It only has 1 outer flat pocket.
The lunch box is circular. It's forward-facing modern Sonic where is face is the whole circle. They add flat flappy ears & mini spikes to the edge of it. Notice that the plasti-fabric for the face is a little shimmery. The effect...is another of those "Well everything could be Sonic's face" where you can tell they were kind of shoe-horning the concept in there.

How good this would be for fitting a lunch inside is unknown since it's round. The 3rd item is the ever unseen gel-icepack which is unbranded. Then there's the unbranded water bottle. The final item is the zipper pull. It's a squeezey-squish blue sphere that's supposed to represent rolling Sonic but it is just an unbranded sphere.
Disregarding (ish) the unbranded stuff, it's still a cute set for little kids. It's also interesting to see 'gotta go fast' on an official item like this because it's from Sonic X (which this is not) and was originally coined to make fun of Sonic and the show for having such a kooky theme song. But instead, it developed into a slogan. This is a 2019/fall item.
