In a comment on a recent guest post, a reader asked about the availability of A5 binders to store archived Filofax pages. The Filofax post storage binders make it hard to read or photocopy completed pages.
In Europe, there's not much of a problem. A5 2-ring binders and hole punches are everywhere. (You need a separate hole punch, because none of the 6 holes in Filo paper line up with the 2 holes in an A5 binder. Funny, that.)
But in the U.S., A5 paper and accessories are very hard to find. You can possibly find items in the Japantowns of major cities, as I did in New York last year.
Recently, I found another source, located in Massachusetts, that will ship anywhere in the U.S. It's Empire Imports. The #1075 binder on this page is A5 size. There's only one color (dark), and only one spine size (3"), but it's available in the U.S., it holds tons of paper, and Empire Imports is increasing its selection all the time. For example, the company recently added reams of A5 paper, so you can print your own Filo forms. You can also get hole punches from them.
(By the way, if you need A4 or A3 paper and accessories in the U.S., Empire Imports has an even bigger selection.)
