Tank case

[Mr Ripple]

The little metal pot you get with the tauren and tauren one are just what you are looking for.
Tank screws into the base and base screws into the top

If you can still get them a 35mm film canister might be ideal to fit a tank in.

Edit: 30mm inner diameter , 54 mm hieght

I usually carry 3 or 4 setups with me when I'm out for the day, but I wear jackets with many pockets.

Sum canny suggestions . Only got me wondering after i went for a walk up the woods with my Dtl and i sat blowing vape clouds through the trees and then popped into town for bits and bobs, the looks i was getting using my falcon tank was worse than a cigge. Think i'll just stick to Mtl outside n Dtl when indoors .
