@[x1ii] Hey, welcome to the WBO.
We can't really answer your question without pictures, so please post them in the appropriate thread,
the Plastics Q & A. If you don't know how to post pictures upload them onto an image hosting site like Imgur or Photobucket and post the link. If you're unable to do that, provide us with a link to the eBay page, and we should be able to tell if it's fake or not.
For future reference, questions like these do not need their own topic, and should be asked in one of the Q & A topics that you can find with the search function in the top right corner (I have several of them linked in my signature also).
