Expanding Pockets & Folders

For projects on the move, expanding folders add the capacity and closure you need. Choose file pockets and wallets with Tyvek®‑reinforced sides for 3.5"–5.25" of expansion and a flap‑and‑cord closure to keep contents contained. Or pick accordion organizers with 13–21 pockets—indexed A‑Z, monthly, or blank—for portable sorting.

Redrope classics offer rugged paper durability and recycled content; poly styles add moisture resistance for field work and commuting. Either way, you’ll keep discovery sets, case packets, and client documents organized and ready to travel.

Enjoy bulk pricing and free shipping on orders over $99 (contiguous US; exclusions apply).
