Both MInkus binders, the one designed for the Supreme Global and the maroon binder above designed for Minkus country pages, are awkward to use, at best. Back in the day, Minkus used to make a very nice 2-post country album with a curved spine (or "back," if you prefer) that was very comfortable to use. Comfortable because the curved spine made it easy to hold, and because it was narrow enough, and not overly heavy, so you could actually pick it up with one hand.
If an album holds too many pages, and both of these Minkus albums certainly do, it gets very heavy. And if the spine is flat, it's very hard to hold in your hand. This is why both of these binders just don't work well. With the resurrection of Minkus by Amos Advantage in recent years, they really needed to create a useable binder. But they haven't. Finding a happy alternative binder which holds only a few hundred pages, so it's not too heavy, and which has a comfortable (preferably curved) spine would be the best way to solve the problem. But the two-hole punch Minkus pages have will not fit any other binders. That means you're going to have to hole punch all the pages to fit some other binders.
Minkus pages can easily be hole-punched to fit into a three-ring binder. You can either do that yourself or have a print shop do it all for you -- assuming you don't mind handing them all your album pages which might have stamps mounted on them! I'd get a heavy duty three-hole punch and do it myself. You'll end up with five holes in each page, but you'll hardly notice that. Put the pages into a suitable larger three-ring binder. I'd use binders that look good and hold up over time. Check page size so you know which size the binders need to be -- obviously bigger than the pages you're using. I'd buy one potential binder and hole punch a couple of Minkus pages to fit it, just to be sure it works well. Some of the Lighthouse Vario type binders might work. They cost $30-40 or so. Ordinary American three-ring binders from the office supply stores are inexpensive (maybe $10 each), but they look that way, too. Personally, I'd aim for something a bit more elegant looking.
Britain and Europe also commonly use four-ring binders, and it's easy on EbayUK to buy an inexpensive four-hole punch to make the pages compatible. Some of these four-ring binders are very nice, sometimes padded, often with slipcases. And they aren't too expensive, maybe $25-50 each depending on the brand and features.. Worth considering. Good suppliers of these are Dauwalders Stamp Shop, Prinz, Stanley Gibbons, and others, all with good websites. Or use
ebay.
Another alternative that looks very nice is to use 22-ring binders, a common choice in Britain and Europe. The binders are easy to buy, but you'll need to locate a 22-hole punch to do the hole punching, and that won't be so easy.
If you use smaller binders, I'd guess you'll need three or more for every volume of the Minkus Global you have. But you'll end up with smaller, more comfortable albums you can actually pick up. And it will be much easier to take pages out when you need to..
