For back to school in fall 2020, here is a new 5 Piece Sonic School set. With this set you get the usually shaped school backpack, a soft sides traditional 'lunch bag' shaped insulated lunch carrier, a plasti-fabric pencil case with zipper top, a re-freeze-beads ice pack square & a black sport top water bottle.
As seems to be a bit of the usual with sets like this, 2 of the items are unfortunately generic. The black water bottle is a regular plastic blank bottle, and the ice pack uses blue gel re-freeze beads but it is also generic/not a Sonic thing.
The theme here seems to be 'checker faces', but the variety of characters featured keeps things novel and colorful. In the checkers you can see portraits for Sonic, Tails, Knuckles, Eggman, Shadow AND Silver. Between them in the black squares are their names spelled out in the modern logo font.
The school bag uses black/gray checkers with character silouhettes instead.

Notice the top part of the bag with the CG/Full color for Sonic, Tails & Knuckles. It uses sort of plastic fabric that has a texturing in it that creates bands of sort of shine/sparkle across it. You can see that texture starting on Sonic's face a bit & in the sky. It looks neat in person but is difficult to photograph.
The lunch bag's style is new...being shaped like a fold/over paper bag but made of that keep-cool plasti-cloth. It has the checker/faces, but the top flap has CG Sonic & 'idea/pointing up' Tails. This is a nice set with good detail! It's relatively inexpensive on Amazon too...a nice choice!
