Four flap enclosures are a safe, effective method to store documents and pamphlets without boxing or attaching them to a case. The enclosure fully protects and securely holds your material so it can be easily shelved. The precision die cut 10 point inner four flap with a single spine score is attached to a 40 point outer folder with a green Library Summit spine that allows easy labeling. Both are made of sandstone archival board. Available in a variety of sizes, the four flap enclosure safely covers your important documents for long-term protection.
The four flap enclosure allows you to open the folder and all four flaps, place your document or pamphlet in the center and close the bottom, top, right and left flaps.
