What you get

  • Paste the exact real ISBN values you received from the agency; Fitinty validates each one and creates a real, exhaustible batch, never a fabricated number.
  • Practice batches are clearly labelled, never real and never usable on a published book.
  • Low-inventory alerts before the batch runs out.
