Hello guys, I really need your help.
I hope you guys doing well. I would really appreciate if you help me figuring out this one is legit or not.
This has a strong magnetic cap.
Batch code on the box can be searched : made in 2017
but there is no batch code on a bottle. Thank you.

I put pictures below , thanks.

Thank you for your reply. This cap goes badk and forth everywhere, I ve heared that authentic cap can't move like this...
