Hello everyone, i'm new here on this forum, and this is my first post.
I have recently been offered this incredibly beautiful pen (in my opinion) But i am unsure of it's authenticity, it looks authentic in my eyes, but i thought i would have some extra eyes to help me out. i would also love your opinions on this pen, and if it's worth it. It's a S.t Dupont Laque De Chine, all certificates, 4 extra refills and box includet. The seller is asking $100.
Here is some pictures:

i'm sorry i had to use lightshot, my attachments wouldn't work.

I hope you want to leave your opinion on the pen and help me out, will be much appreciated!

Thanks in advance!
