So I've bought two ties on eBay from this seller (ilcravattaiomatto). To me, they are certainly fake:
1. Their touch is very coarse, coarser than my grocery bags.
2. The patterns are poorly printed (look at the blue and red running into the white areas).
3. The lustre suggests polyester.
4. The general miserable looking upon close examination resembles ties sold at $ 2 in China (maybe less).
