Office organizers, these Smead file pockets are absolute workhorses for document management! The legal size (15 3/4 x 9 1/2 inches) is perfect for holding standard legal folders without any bulging or awkward fitting. The 3 1/2 inch expansion is genius - they stay slim when you don't need much space but can expand to hold up to 400 sheets when your project grows. The accordion-style sides are reinforced with tear-resistant material, so they can handle heavy use without falling apart. The dark brown gussets not only look professional but also help with color-coding your files by case or subject. The 3/4 inch straight-cut tab is reinforced for those frequently handled files that get pulled in and out constantly. What's really impressive is the construction - double thick redrope reinforcement front and back, plus 6 1/2 inch high fully lined Tyvek gussets that can take a beating. These are the same file pockets favored by law firms and other document-intensive industries because they're just built better. The fact that they contain 30% recycled content with 30% post-consumer material is a nice bonus for environmentally conscious offices. Smead has been in the organization business for over a century, and you can really see that experience in the quality and thoughtful design. Whether you're organizing legal documents, project files, or important records, these file pockets provide that professional, durable storage solution that keeps everything neat and accessible.
