I just got 3 attys from cignot and when I opened them up 2 of the atty's fibers under the wick bridge are all frayed out with one of the bridges is bent almost all the way touching the side. The 3rd atty is perfect but the first 2 are bothering me. I havent used the frayed attys yet, but will they work normally? Or is this a manufacturer error and should I send them back?
