This is what we, DELTAone call this initial scratch on the Heart Wheel Feather.
As you could see, this scratch seems like NIKE logo!
It could be seen the behind of the wheel part.
The same mold is basically used for both All Gold Heart Wheel Feather and Silver Heart Wheel Feather.
This initial scratch therefore would be seen for all of them. It might be shaved and became lighter, however less likely completely gone.
And most importantly, it should be seen on only L size, not S and M.
The initial scratch could be on the several types of item of goro’s.
And it tells you if it is real or not. It is pretty interesting, isn’t it😉
