What is this oil? (wet lube) I needed wet lube for my chain, so I went to my local cycle store and bought the following pictured Shimano wet lube.

Back home, out of curiosity, I "googled" it, and surprisingly enough, I didn't found any picture of it on the Web. Now I'm really wondering, do you guys have any idea of the origin of this product?

The label is in Dutch, French and Danish. The company is noted as "Shimano Workshop > Shimano Europe", headquartered in the Netherlands. The only reference number is WS000002-A.
I think you probably have Shimano's wet lube.  Confidence could increase if you feel that the point of sale was a reputable store with legitimate distributorship.   Speaking of all that, are you a believer that Amazon represents a company like that?   Here's an Amazon post in which the label appears very similar and the manufacturers reference number begins "WS..." 

While this rationale is fairly weak counterfeiting a relatively inexpensive product isn't cost effective, legalities aside.  As they say, "the proof is in the pudding," so I would try it out and see how it works out.
