This is the "Sonic Big-Face 2 Compartment Lunch Kit".
It is made of a nylon canvas material, including the flappy spikes & ears. It's a forward-facing classic Sonic fave on a plain blue background. So, another item meant to 'be Sonic's head' that stores your stuff. There's a handle at the top for carrying. The back/bottom has an all-embroidered full color classic logo. It works almost like a school bag that it is shaped like. There's a main top arch shaped area & then the black area has a zipper around the top to create a rectangle space.

This is supposedly at Amazon in fall 2019, but is also somewhat costly at 30 dollars. Is it super big? Very thick? It likely wouldn't fit into a school bag, maybe it is meant for work lunches / offices?
