These were cases Topps used for uncirculated cards/boxtoppers in the early-mid 2000s. I don't know where you can get new ones, but at worst, you could probably buy cheap uncirculated cards and crack them out.
Probably not possible due to standard binders, but when I heard of these, I was hoping it was at least 6 per page. I dislike that large gap in the middle.
These are cool, but I think I'd honestly prefer a sleeve type system that's big enough for one touches. The thin plastic doesn't look like it would hold up for very long if you're flipping through it often.
I meant to show that on video and just forgot...I even had the binder on the side ready to go lol. It looks pretty similar to the PSA pages I showed a little over a week ago. Bulky and if you had 5 or 6 of them, it would fill up a thick binder quick.
