I also see there is a cotton like think in subbox mini. Whis is this for? And the 1.2 ohm coils is for direct use. I mean open the packet and just use the coil or I need to open coil and setup it?

Like AW said, you wil be getting three coil heads in the box.

There's three coils:
-a 0.5ohm coil for direct lung inhales
-a 1.2 ohm coil for mouth to lung inhales
-a rebuildable coil to make your own coils on.

It's recommended that you use the 1.2ohm head first, since that will give you the closest vape experience to your vape pen.

How long have you been using your pen? Have you ever had to change the coil heads for them before?

Here is a video on how to use the tank and change the coils on this tank: Kanger SUBOX Mini Kit Detailed Review w/ Updated Subtank Mini

You can try using the 0.5ohm head later and see if you like it.
