asking for more info on the e-cigs. okay. Here’s a pic of the pack open, which you charge the cigs in the pack, the USB or wall charger connects to the pack. There’s a little spot on the bottom of the pack. Then there’s a light on the side, when the light goes out, the cigs are charged.
Inside the pack, there are five slots for your cartridges. And two spots for the e-cig.
The picture shows the pack open, and the cig broken into it’s two parts, the smaller part is the flavor cartridge, you screw into the larger cig part. there are videos on the web site. I’m sure the ‘professionals’ can explain this as well, if not better. lol

anywho..hope this post answers your questions. Easier to reply to 20+ emails this way. Thanks for reading!
