If it would be very well-made I would indeed love a binder like that. I currently use a regular binder with loose 9-slot binders I can add. But since I have over 1,000 Pikachu cards, and it’s not going to slow down anytime soon, I wouldn’t mind a massive binder like that.
PS: Here you can find my current three binders for main Pokémon collections (however, I also have eight more of these binders, four for Pokémon and four for Yu-Gi-Oh, and about 7,500 loose cards in a cardboard box… But those are for my entire collection, instead of just the parts I focus on now.)
