Purchasing this binder seemed like a good good first step toward my goal of an office that smells of rich mahogany and is filled with many leather-bound books. The binder and case are leatherette, of course, but they still look great on the shelf. Not only do they look and feel high quality, but the binder does a great job for the purpose I actually ordered it for -- storing a small collection of first day covers.To start with, I purchased one set of 25 Lighthouse VARIO 2S pages - Professional Pack to use in the binder. So far, I've filled up 22 of the 25 sheets. The description for the Vario-G Classic Binder says that it will hold up to 80. I can help but wonder if that's 80 empty sheets or perhaps 80 sheets with material thinner than the first day cover envelopes. Right now, it looks like 50 sheets full of envelopes is a reasonable goal for me. Your mileage, of course, may vary.
