Seems to be a genuine part.

In the sales display gives the impression that it is in the protective cap for the hot shoe is an original part of Nikon.
However, this is not the case but it is merely a replica (there is no cap on the bottom of the label Nikon BS-1).
This fact is not mentioned in the sales display.
Part is still fit and optically corresponds to the original.
However, since replicas are available for considerably less money here, you feel something verschaukelt, also the original part at Nikon for 5, - is available.
