You are buying 1 blue filled Syringe pen. It is the same identical pen produced for the Zombrex game, but without the expensive label. It is the same one that came in the Zombrex edition, except it does not have the label of the word Zombrex.
This is not the official item that came with the game.
There in no box or Zombrex game. You will receive 1 new Syringe pen packed in bubble wrap.
