There's always something going to bother somebody and as long as you're honest, you don't have to be worried or feel bad about it. I'm allergic to most detergents and fabric softeners, so if it's ever going to touch my skin (including a bag or hat) I have to wash it a couple of times.
However, it is only MY responsibility to look out for my allergies, NOT the seller's, and it has never stopped me from buying something I liked.
If others feel differently then they can purchase from someone else, right?
