Heavy-duty binder features a locking mechanism that lets you open and close the metal round rings with a single touch, making it easy to add or change contents. Clear, nonglare, one-piece overlay on front, spine and back allows easy transformation into a custom binder, perfect for presenting your work. The CleanView polypropylene material resists ink and toner transfer so printed papers won't stick or mark binders. Four stacked opaque pockets provide maximum storage. Binder also features a sturdy chipboard core.
