maybe mine isnt cotton either but i have heard some high end ones used cotton. i have a high end one. idk what it uses. i should check.

thank you for the info.

idk how flammable the liquid is. and then take into account the battery like you said. im afraid. because i had an accident with one of my ecigs. the button got pressed in my bag while i was walking in the mall so it was like "vaping" while i was walking and browsing-pretty much going off. and it got EXTREMELY EXTREMELY EXTREMELY HOT. i mean hot. i thought my bag was gonna catch on fire. i went to the nearest mall entrance and took it out and took it apart and it had liquid coming out of it. even the battery. liquid had escaped out of the tank into the battery compartment. i was so nervous. im never using that brand again or that ecig. ever. i bought another one that day. i just couldnt believe it. it was a nightmare.
