Have you emailed the seller to ask? I would! If you don't get a response you might want to pass on it. Worst case scenario is that it's ink and that might never come out.
ETA: Okay, I just found the auction. There's a good chance that you might not get a response from the seller seeing the end is so close and because they are high volume sellers. The price is still quite low so I guess you have to ask yourself if it's worth risking the money on it.
