Thank you for trying to help.

There is some "engraving" on the clip, so small that even with magnifying glass I can not read it, so perhaps is not even writing but just marks.
I bought it for the hang tag and I was going to sell the tassel as I am not going to use it, but I needed to be sure, so when I asked the ladies of the authenticating thread, I was told that was real but perhaps a promotional item.
I know the hang tag is real
Coach, the box is also real Coach made in 2016, so the item/items had to be sold on 2016 or 2017..?
I can read Chalk so it is the color of the items, and JAX. Could it be an Outlet gift set?
I have searched in all the places I could think of. I have found tassels like it made by Michael Kors, but the cap is engraved and are all in silver, no matter the color. I also found one exactly the same by Victoria Secret, but the rest (clip, ring) were different.
I am starting to believe there was something also that size on the gift set, that was swapped by the "generic" tassel, although not even with China made, I could find one like it on Ebay or Goggle.
