I think I've read somewhere sometime ago that they are just Hangsen or Dekang juice which I can get from many other vendors
FWIW, the smokeless image 555 is damned near identical to the V4L WOW 555. someone had mentioned that in another thread, so i ordered some to try, and the only difference i could find( just might need to steep) was that the SI 555 wasnt quite as sweet as the V4L stuff. other than that, the smell and taste were almost identical. if you could find out where they get it from, it might help track down where the V4l stuff was made.
