TAC Vanes -Bent?

[CB4]

Why does it seem like one out of every three TAC vanes has a bend to it out of the package? I’m talking about a crease in them if you are looking at them from the back after installing on an arrow.

TAC vanes are great in as far as flying well and being quiet, but they just aren’t worth it to me. They take a permanent set really fast and are a pain to adhere. If they get bent, even in the package, they are that way for good.
