How you use our 3-ring binders
A binder earns its place by what you can still find in it in May. Ours tell you what they hold before you open them: the clear overlay takes a printed cover and a spine label, and the ring size is printed in sheets, not in a spine width you have to measure.
Pick by the stack of paper you have now plus the stack still coming. A science class with weekly labs fills a 1-inch binder by winter break; a binder per course of 1.5 inches lasts the year. For tax papers, medical records or a recipe collection with sheet protectors, go to 2 inches and count each protector as three sheets.
The covers are polypropylene, PVC-free and non-stick, with two pockets inside for whatever is not punched yet. Pick the colors to match your dividers, and the tab and the cover say the same thing.
Our 3-ring binders are one of five shelves of the SUIN line, and all 24 products stand on one list with their prices.

Questions
Questions about SUIN 3-ring binders
How many sheets does a 1-inch SUIN binder hold?
Up to 200 letter-size sheets on round rings. The half-inch holds 100, the 1.5-inch 325 and the 2-inch 450. With sheet protectors, count each one as three sheets.
Can you put your own cover in a SUIN view binder?
Yes. A clear overlay runs across the front, back and spine: slide in a printed cover sheet and a spine label, and change them when the binder changes job.
Are SUIN binders PVC-free?
The covers and pockets are polypropylene and PVC-free. Archivists keep papers and photos in polypropylene, so the plastic does not lift your printing.
Which SUIN binder fits a backpack best?
The expandable-spine 1-inch binder holds 175 sheets when full and slims down when it is not. For a planner-size bag, take the mini A5 binder.
Do SUIN binders come in bulk for a classroom?
The basic 1-inch binder comes in packs of 12 and 48, and the view binder with pockets in packs of 12 and 36, in 0.5 or 1 inch.
