This is called the "Sonic Essentials 5 Piece School Set".
And the 16 inch backpack is glittery! See it sparkle in the magnified inset there at the left. Can you spot all 5 pieces? First is the school bag itself, with big glossy CG graphic of Sonic in front of a Green Hill type background. The bag has 2 side mesh pockets, carry handle at the top & shoulder straps. It has a thinner front zip pocket. Second is a pencil case (flat thing to the right) with zip top. Third is the matching 'mini bag' that features the same red Sonic line art & yellow logos with red trim. Fourth is the generic white water bottle with black top. Did you spot the fifth? It's the red aluminium Karabiner clip dangling from the extra loop at the top of the pack. You can use this to clip the mini bag to it. So really, it's 3 Sonic things and 2 generic things. This is a 2017 item, and should be only 18.99 for the set, which is a really good rate for 3 things under 20 bucks. Plus! It glitters!
