I use the product for filing documents (both personal & business). I also use the larger sizes for reports and small periodicals. I love that there are sleeves inside the front and back covers and the rings are very easy to open.
This is a fantastic binder. You can open it with one hand and don't have to worry about holding down half of the papers when it gets full since the rings are "D-rings" (meaning shaped like the letter D instead of completely round). I keep all of my recipes in there in plastic cover sheets and it's just perfect!
