When I was searching for a card holder to protect my really thick memorabilia cards greater then 120 pt. I discovered these. I found them to be of good quality and a decent price. They are easy to use.
So far holds pretty thick cards. Still I don’t know the pts for size of cards, most of them don’t tell me anywhere When I purchase a valued card, they come to me in top holders and then I have to put them in these better card holders, just not right
