Hi,
Thank you for your recent purchase of Five Pawns.
While it’s nearly impossible to authenticate liquid via email the concerns you show below don’t really determine authenticity.
A Omg bottle will be nearly clear quite often depending on the flavor whereas a 6mg bottle will be darker. However, color is no taste determining factor, it simply means that the bottle could be older or have been exposed to more light. (even pre-packaging)
The flow restrictor, while required in the US, is not on International bottles. If you are in the US, then that was made in error but would not affect authenticity either.
Naturally, a 6mg will have a slightly different flavor than a 0mg with the addition of nicotine.
Hope this helps
Jessica
