Unfortunately, not enough, too bad, because I had expected better and I had very happy. Three stars are there only because the service was very quick and at least two of the springs write reasonably well. In particular, the wider springs not write. The ink does not seem to flow sufficiently. I've tried everything, both the ink cartridges (at least one) and the "tank" I can no longer set the return.
Deluxe not true, unfortunately front and rear. The springs and the filling itself seem very cheap - just plastic housing and springs made of sheet metal with "gold plating"? At least that seems to the set. The box is once again appealing, but with whom I do not write.
Can not really recommend in good conscience I. A real shame.
