Pocket counts vary by style: basic folders commonly have 2 pockets, while expandable or organizer-style files can have 7 or 8 pockets — overall ranges in listings are roughly 2 to 8 pockets.
Most poly folders are made to hold standard US letter paper (8.5 × 11 inches); some expandable files also list compatibility with A4 as well as letter sizes.
Common options include metal prongs, 3-hole punched variants for use in binders, non-pronged styles, and closures like elastic bands on expandable files.
Listings and reviews describe these folders as made from tear-resistant, durable plastics with water-resistant (and in some cases described as waterproof) covers. Many notes emphasize sturdy construction and long-lasting use, especially for school or daily use.
Options range from assorted multicolor packs to themed prints (for example floral or pressed-botanical designs). Some listings note that exact colors or patterns may vary by purchase.
