10 x 11.5" is the size of Scott Specialty pages, so according to the dimensions given on this website, they would fit into these binders but it would be kind of close. I'm going to guess that the pages might be so tall they might brush against the thumb device at top or bottom -- or stick out the side too far for comfort.
Usually people gravitate to ring binders for their stamp album in order to save money. With these, I think you'd just be wasting money and spending more than buying a higher quality Scott 3-ring binder.
These look like cheap cardboard binders fancied up a bit to sell for a really high price. I'd never use this sort of thing for a stamp collection I cared about. Even the cheap little tab they've added to the bottom of the binder to allow you to remove it from the slipcase is going to less effective than the much more straightforward solution of making your slipcases with an indentation on each side -- the way Scott slipcases are made.
The rings lack pin-into-hole ends which work best. Instead, they use the kind of ring ends that tear up pages so well unless you're careful. This is particularly a problem on binders with large rings, less so on small rings which close more accurately.
Why not just use Scott Specialty binders? Or if you want to save a few dollars buy some on
Amazon of the "leather" type such as We-R-Memory Keepers which are good-looking, well made, and not so expensive. And Scott Specialty pages will fit in them. No slipcases, though.
If I used 3-ring binders, I'd use the smaller size Scott Specialty binders in their slipcase. They're well made, good looking, and easy to handle. And, believe it or not, they fit Scott Specialty pages perfectly! Why not use the large size 3-ring binder? That size is enormous, and I find it unpleasant to try to pick it up or even to look at, it's so large. On the bookshelf, it's so big it sticks out a few inches from the edge of the shelf which looks ridiculous. The smaller Scott 3-ring binder does not have these problems, but you'll likely need more binders, of course, to hold all your pages.
