Customs will not be searching little FT envelopes for items violating trademarks.

They may open boxes, crates, and shipping containers, though.

FastTech is a small player in the whole scheme of things. What customs will, and should be checking into is wholesale fraud; vendors buying these products en masse with intent to distribute. They don't give a shit about personal use.

That said.. Who gives a fuck if knockoff Hana and V3 products are seized? Those products are so far from my WANT! list that they're not even sitting in my wishlist.
