The Wilson Jones W326-10W is a white, 1 inch mini binder that holds up to 220 sheets of 8-1/2 inch x 5-1/2 inch paper. Despite the unique size, it still functions like a basic three-ring binder. Sheets are instantly secured by the three traditional round rings with top and bottom open-and-close triggers. Any unpunched papers can be stored in the pockets on the interior of the binder covers. The view cover allows you to show off your style and keeps all your papers together. The front cover, back cover and binder spine include a clear overlay. Insert cover pages and a spine that you create and it will be obvious which binder is yours. The view feature also makes it simpler to reuse your binder. Switch out your custom covers and spine as often as needed to use your binder for a different subject or project. A mini binder is a great tool to keep papers organized, and take notes on the go. The new PVC Free polypropylene construction makes this binder more durable and safer for the environment.
