I have a few questions

about the sample packs...

I have sample packs of..
* Alter Ego
* Chikara
* The Edge for Him
* Scent Of

Eros

Questions:
1- What type of SOE is this? It doesn't say "for men" or anything on the pack.

2- Alter

Ego, Chikara and The Edge for Him...Are these single use packs? I am not really familiar with these products yet.
