It looks like that
Amazon listing includes a set of 300 mixed-size 2x2s, as well as the album pages to put the 2x2s in.
That's fine, so long as the coins you want to house are the sizes which they've supplied. The picture, at least, shows a range of sizes from dime to silver dollar sized. You'll need to buy extra 2x2s if you're wanting to use all the album pages just to house all of your Lincoln pennies, for example.
These are made-in-China generics, both the pages and 2x2s, which is why they're so cheap, so the quality may be variable.
For me personally, when buying coin album pages for 2x2s, I always go to a photography supply store and buy the pages they make for 2x2 photographic slides; slides are the same size as 2x2 coin holders, and slide album pages tend to be made of much higher quality, more archival plastic than the people who make "coin album pages" tend to use. Vue-All, from PrintFile, has been my go-to brand for decades. And yes, I have to import them to Australia from America, now that my local photography supply store has gone out of business - I think they're worth it.
Here's a pack of 25 pages for US$8.95; at 20 coins per page (the same as the
Amazon pages), that's room for 500 coins. You'll need to buy the 2x2s separately from elsewhere; I normally just go down to my local coin dealer and pick and choose the sizes I want at that moment.
PrintFile also sells
these excellent archival 3-ring binder-boxes to put the pages in. These binders are excellent for coin collectors in several ways: they're not airtight but they are fully enclosed, so no dust gets in; they're easily stored sideways (ring-side-up) so there's less drag from heavy album pages pulling on the rings, and best of all, you can stack them up on top of each other if you need to, and not have to worry about the coins in the albums on the bottom of the stack getting squeezed by the weight of the coins on top (which can cause solvent transfer between the 2x2s and the album pages, making the 2x2s stick inside the album pages).
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
