The Janty (Twisp) made e-cig's have great cases to carry the batteries, atomizers and even chargers.
BUT, we all need a case similar to analogs. Yes?
So I decided to make my own:
First I "undo" an analog packet to see how they did it, modify it (so that 6 e-cigs can fit - three in a row of two) with an A4 paper and use a plastic paper binder.
Scratch the lines with a sharp object (not cut!), fold tight, use quick dry glue, and I have my holder.
To make it more respectable I use a piece of canvas and stick it around with wood (or similar) glue.
The flap do not always want to close (and the first one break off) so I work it with a piece of canvas as hinges, stick a piece of velcro both sides instead of press-studs.
Want to be fancy? Use leather.
