I’m a new collector who’s trying to find the most effective way to keep my cards in good condition. Atm, all my cards are in top loaders but I really want to buy a binder for them. However, everytime I'm ready to get one, I come across someone's horror story about cards getting bent/warped overtime inside binders.

In your experience, what's the absolute best binder that one can buy to protect their cards?

Btw, the PTCGO guys are bullies
