This is a set of Boom Backpack Hangers.
And, it's a company photo, so why didn't they do a better job of it? There's wierd texture all across the top like some popcorn-ceiling or static stuff. As you can see from the bottom photo, they were blind packaged in round foil bags and dispensed from the usual cardboard drop down tray.
Judging by the fact that the clip top thing is almost as large as the figure, they're not likely to be big. The pose variety for the characters is nice...everyone is active and looks pretty on-model. However, they chose 4 of Sonic so that's a little rough. (Maybe to avoid Orbot or Cubot figures?)
Plastic hanger clips are never a good idea to actually put into use. The chance of losing the hanger toy is pretty high with them, especially on a rough n tumble backpack. If you do get these, it's probably best to either hang them some other way or just use them for display in a collection. A blindpacked 'cheap' (they probably weren't but) item like this isn't going to have fabulous durability in the construction. Where were these sold?
These are Sonic Boom "Backpack Hangers".
There are 10 different mini figures & they're blindpacked in these sort of shaped bags. You can get 4 different Sonics, Knuckles, Amy, Tails, Eggman, Sticks or a 'mystery figure' that....is very likely to also be Sonic. Why so many Sonics? Why not Orbot or Cubot? Where are these sold? The package seems to be in English and likely also French, so that gives a variety of possible places.
