For two e-cigarettes the Etuie enough good, who wants to carry but still charging cable, AC adapter, Liquid (s) and disposable gloves (for filling !!!!), should get used to a handbag if possible before. I am thinking of the unspeakable little wrist models from the 70s. But since you have to have the courage now. Messenger are there probably more hip, although I also scoff at my daughters with such a thing ...
My current favorite (coming for example on working perfectly with just one electronic Glimmstengel including filling) would be more like a liquid-tight cigar tube. It fits in your jacket / pants and protects clothes from accidental leakage of liquids. This can not really next to the desirable odor lead to evil poisoning by skin absorption. Heretofore is astonishingly and never justifiably hardly warned. Have when filling little nicotine Liquid gotten by the hand and was about 12 hours under "full steam ahead", which was not pleasant safe.
