Jazz e-Mystick (D10) works just as the big seller V10, but unlike the V10 is not rechargeable. Jazz e-Mystick holds about 400 inhalations and can be used when ever you feel like it. It won't be damaged if not used for a couple of days. Jazz e-Mystick will initially be available in colors white or brown in classic cigarette flavor and menthol. The size of the D10 model is a bit smaller and lighter than the classic V10 cigarette. A fantastic product that is also recycleble!
