I just bought these and a .5" binder to store my GH item shop. I've also sleeved my item cards and these sheets can fit two sleeved cards in each slot. The sleeve sticks out of the top of each slot (I can add a picture later) but it makes the items easy to grab out of the pockets.

I say no. I got these: https://www.amazon.com/gp/product/B01ARJ9AT0/ref=ppx\_yo\_dt\_b\_search\_asin\_title?ie=UTF8&psc=1, which are 41mm x 63mm and sometimes if I turn the pages too quickly, the cards will start to sneak out. I'm pretty sure I've lost a card or two in transport because of this.

I would not trust anything bigger.
