If you bought them from Midori or Nomi-san I can
tell you they are 100% legit and direct from Madhouse.
Hankens don't necessary have to have registration holes
or numbers since they are intended for products
not production.
Some of my DN hankens have 2-3 sketches, one a pencil
sketch, a 2nd is a photocopy of the pencil sketch w/ hand-colored
shading, and the 3rd a rough sketch.
Just remember, that these are scanned into the computer
and colored in photoshop or painter, meaning the label
could very well not be drawn in because they already have
a pre-made/stock layer in either of the 2 programs that they can
just plop into the final drawing.
Hope this info helps!
Also, congrats on the gorgeous hanken!!
Its really hard to find anything from Black Lagoon.
