Collecting Binder page for sealed Japanese Boosters (Storage/Display)


Aspiring Trainer
Hi everyone :),
I have been on a quest to find a binder page that can hold Japanese boosters well.

So far I have found:
1. "100 Ultra Pro PLATINUM 4-Pocket Toploader Pages" on Cardmarket

2. "Ultra Pro Platinum-Serie Toploader 4-Pocket Secure-Seite"

I have also looked at further sites. However, no one seems to be able to give me measurements of the pockets.

I can't be the only one who wants to collect Japanese Booster sealed in a binder. Does anyone have any advice? Would be greatly appreciated ?☺️
