I checked with the DHS page. The code was authentic. Also have red rubber from same source which was fine. Both codes were confirmed as genuine. Also, not the first time getting the hurricane with a fingerprint.
I have been wondering this as I bought quite a lot of Palio AK-47 Red (black color) and those "smudges" / "finger prints" are almost always present. The red color is fine though. The rubbers are brand new out of the factory packaging. But it does not affect the way they play though.
Back to the topic, here is my theory.
I believe that the cost of making such blades are not that expensive in China. But since it bears the name of The Great Ma Long, then the selling price becomes very expensive. This is what Butterfly has been doing for a long time and now almost every TT manufacturers do the same.
However, I believe that if we pay such a high price, they need to, at least, pay attention to QC more.
