three hole pocket folder

Most 3-hole pocket folders and binder pockets are sized for standard US letter paper (8.5" x 11") and will also accommodate small receipts when used with clear binder sleeves or folders designed for binders.

Common materials include clear polypropylene plastic sleeves, paperboard or paper folders (often with laminated, water-resistant surfaces), and heavyweight cardstock (300 gsm) used for decorative paper folders.

Most products are pre-punched for standard 3-ring binders. Fastener styles vary but typically include non-pronged options and some pronged fastener styles; many listings explicitly state "3-hole punched" for binder storage.

Pocket counts vary by product and include single-pocket clear sleeves, 2-pocket and 4-pocket folders, and paper folder sets that list higher counts such as 9- and 12-pocket configurations.

Common orientations include vertical and horizontal pockets. Some paper folders specify mixed layouts—for example, two vertical and two horizontal pockets on each side—to accommodate different document sizes.
