Fake / Counterfeit Siltech cables ???

I guess somebody has posted an ad indicating counterfeit Siltech is rather widespread in Asia.

So I recently purchased an Siltech FTM3 with WBT 0150 Locking RCA from another Audiogon member. When I got the cables, I noticed the jacket has *nothing* printed on it. The jacket condition appear to be good so I doubted if the original print has faded. That gets me very very worried.

Does anybody own Siltech FTM3 before and could enlight me if this is normal? Thank you.
