The grey and yellow one... what specifically about that one, makes you think that one is fake, as I'm trying to figure that out, for Canali. I figured the repeating Canali on the inside backing was probably pointing to that, but is there anything else? I've seen a few of them, and some I have picked up, but some I've left, as I'm not sure on the Canali ones.
Some of the Pal Zileri ones as well, I'm sometimes on the fence about.
Well that keeper has never existed ever on a real Canali tie and neither has that print on the lining on the reverse of the large blade. Your Zileri is good to go, but that Canali is definitely not kosher.
