Hey guys, I just wanted to ask about dust spots/stains on your cards. How often do you guys find these spots on your cards? It's not the side of the cards, it's the on the face of the cards. Considering the fact that you take really good care of it (washing hands before using etc.). I've had a deck for about a week already. I take really good care of it but the cards seem to get some dust spots on them. Is this just natural to have and just can't be avoided? Sorry I'm kinda new to this so yeah. Thanks!!
