I received a reply and here it is copied and pasted
(Thanks for your email !
Our hot selling KOG , inside is 510 lr atomizer , can vapor good ,and hold 5ml e liquid.)
I think that the first pic in your post shows the
tank upside down and we are looking at the contact post that connects onto the ego style battery via the
threads, I think if we could see it from the other side then we would see where the actual atomizer goes, this might be closer to the fog than I thought but like you said its all speculation until someone has it in there hands. Let us know when you speak with the guy that is getting one. Thanks
