Need Non-frog Help

Hi, I know that froggers usually have their hands in other hobbies, so I need some bug ID. My students recently convinced me to get Madagascar Hissing Cockroaches for our classroom. I'm totally fine with that but was having a hard time finding them locally and for a reasonable price, until today. Of course they are locally and a decent price so I am just a lil bit skeptical and want to make sure they are the real deal. I have attached a picture, if anyone would like to give me feedback I would appreciate it.

Thanks

(I'm 80-90% sure they ARE)...but still...

I will receive 6 Sub-adults
