how big was the bag that it came in? I got a set in the mail and i was wondering if it was the real thing. It came in a 8inch long bag with 16 retainers.

*yet i saw another pic of a guy who was selling a set of skunk2 ti retainers that had a bag that was half the size of what i got in the mail. I just need to know if i got real skunk2 retainers or not.
