Document storage is simple when you've got the right help. Corner Lock Three-pocket Binder Pockets let you store pages of standard, letter-size paper in a three-ring binder without punching or folding. The corner lock tabs keep your documents secure while the durable poly material protects your pages and resists tearing on the rings even with repeated use. The pockets are acid-free and archival-safe and won't lift print off pages, so you can store papers for long periods. Each binder pocket has three pockets. Assorted colors include green, pink and blue.
