If you have it in your possession it would be common sense to show it's condition/the box so people can trust you and assess its state for themselves. If you just post pictures you grabbed off of any number of wholesale sites you are inviting suspicion.
If I was selling something cheap/shady (or if someone was selling me something cheap) I would want to know more about it/other places it is sold. It's not a matter of being nice to the seller, it's about being a cautious and safe consumer.

And it looks like you are right, there is a mens version.
