Morandi Dual-Pocket Document Bag, String-Tie Envelope with Rear Pocket, Professional Presentation File

The External Back Pocket String Envelope – Morandi Series is designed for professionals who value both sophisticated design and organizational efficiency. Featuring a dual-pocket layout, the front compartment is secured by a classic string-and-washer closure to keep sensitive documents safe, while the additional back pocket allows for instant access to frequently referenced papers. This smart construction enables tiered document management (e.g., active contracts in the front, supporting notes in the back) without increasing the profile of the folder.
