These are what i bought and they don't work together:
Instead of buying a book, I recommend buying detachable pages instead. Something like: https://www.amazon.com/Ultra-Pro-9-Pocket-Trading-Pages/dp/B00095M5DQ
Then get a ring binder book from any office supply shop. This way, when your collection grows, you can insert pages in the middle if you want to keep your cards sorted by type and cost.
It seems like poor labelling on Ultra Pro's part. I found these on Amazon. I don't see any flap on them and their labelled the exact same as the ones I have (Ultra Pro, Platinum, Hologram, etc, etc). If you look at the first image in the top post on the box it shows a zoom in of the flap on the ones I have.
