Depends entirely on who made the cartomizers. Where'd you get them from?
If it was V4L, then your best bet is buying the
juice from V4L as they have their own exclusive flavor formulations. Most other KR808 sellers have the same prefilleds (whatever Kanger puts in them, which I would guess is Dekang). (Though I think Puresmoker does their own 'Atomz' flavors for their cartos as well.)
