I take 1 mod with 2 full 18650's, igo w4, kayfun, usually a few feet of kanthal, cotton, screwdriver and my ohm checker in a zipped up sunglass case. Also take a few 30ml and 10ml bottles of juice too. All goes in my backpack while at work.
1 30ml Moloko Vellocett
1 30ml Malibu Sunset
1 30ml Kubrick's Kustard
1 30ml Butter rum Brulee
1 30ml Mrs. K's Apple Pie a la mode
Juice all from Juice By Kubrick.
Only tank system I can count on now is kayfun! The flavor is amazing and NEVER leaks. But it's not for beginners. Lots of small piece's and you would need to read up on building coils.
