This is a re-usable tote bag for any kind of items.
It's all black & was made for Sonic Mania Adventures. It has good, crisp and bright full color / fully shaded art. The logo is also fully shaded (looks '3d' and somewhat metallic) and large toward the top of the bag.
The scene is a new one, that's slightly confusing, though. It shows Eggman in an odd (stone??) chair, sleeping in his PJs. (Note the pom-pom string tie things & the wrinkly look) He has the traditional Japanese 'sleepy bubble' there, and has spilled his mug of tea on the ground. He's also got his pompom sleepy cap as well. (This is interesting to see because, if you remember some old concept art, the main character of the game was originally going to be Eggman in his pjs just like this...but he was good. So, because this art is new, it's based off that)
Then, there's Metal Sonic sitting on the ground and the front part of his head is caved in to a degree, and someone's applied a criss-cross bandage. He's also holding a small flower. Since you can see the red eyes, he's "alive/awake/whatever you call turn on in a robot) but doing nothing as Eggman sleeps with his feet crossed on his head, using him as a foot stool.

Why's he have a flower? The foot stool bit is there to show that Eggman does not think highly of MS at all, because footstools are considered the lowliest & most degraded piece of furniture in a home according to traditional views. (Why to this also...) All together, it's kind of an odd bit for a tote. This is a SegaShop item in 2019 online.
