Staples File Pocket Folders 3.5 in Expandable Sides, Legal Size

In this review of the Staples File Pocket Folders, the bottom line is simple: these legal-size folders are aimed at users who need to consolidate and protect large stacks of paperwork without buying bulky boxes. The single biggest reason to buy is the 3.5 in expandable pocket, which lets you store more documents or folded materials in one folder while keeping them accessible. The pack of 25 supplies enough folders for a project, a busy home office, or departmental use, and the construction balances affordability with reasonable durability for everyday filing.

Key Features

• 3.5 in expansion: The deep gusset lets a single folder hold thicker stacks or multiple legal-size documents so you reduce the number of separate folders needed.
• Legal-size capacity: Designed specifically for legal-size papers, the folders prevent trimming or bending that can happen when smaller folders are used.
• Straight-cut top tab: The top tab improves quick identification and referencing when folders are shelved or stacked.
• Durable construction: Mylar-covered cardboard and reinforced gussets provide more protection for documents than plain paper folders.
• Pack of 25: Buying the set keeps a consistent look across a filing system and supplies enough folders for larger projects or ongoing filing needs.

Who It's For

The folders are well suited for small offices, legal practices, craft sewers storing folded patterns, and homeowners who manage household papers and want expandable capacity. The pack size and expandable pocket make them a practical choice when many files must be kept together without moving to a box or cabinet.

Those who need heavy-duty archival protection or waterproof materials should look elsewhere, as these are mylar-covered cardboard with 10 percent recycled fiber rather than heavy plastic or archival board. If you only need a few folders, the 25-pack may be more than required.

Pros & Cons
