Document cover Narnia adjustable A4 size No.10, pack of 50 (mpn 131651)

Document cover Narnia adjustable A4 size No.10, pack of 50 is a set of protective covers designed for A4 papers and documents. Each cover features an adjustable spine that allows the sleeve to expand to accommodate different document thicknesses, making it practical for single reports or thicker file bundles. The covers combine a clear front with an opaque back to provide visibility of the first page while offering a stable backing for writing or labeling. Supplied in a bulk pack of 50, these covers are intended for regular office, school, archive or home use where economical, space-saving protection is required.

Advantages

The adjustable spine design lets you vary capacity without needing different sized covers, reducing storage complexity. The clear front panel gives immediate visibility of the document title or cover sheet while the opaque back provides support and hides inner pages from light. Made to fit standard A4 paper, the covers keep loose sheets together and protect edges from wear, dust and moisture during everyday handling and transport.

Suitable for

• Office reports, presentations and meeting handouts
• School assignments, homework and project portfolios
• Archiving or short-term storage of A4 documents
• Home paperwork such as manuals, invoices and receipts

Key specifications

• Format compatibility: A4 sheets
• Adjustable spine allowing variable thickness
• Front: clear transparent panel for visibility
• Back: opaque support panel for stability
• Pack quantity: 50 covers
• Designed for loose sheets, reports and document bundles

How to use

Insert A4 papers through the open edge into the sleeve until the cover holds the stack securely. Adjust the spine by compressing or expanding it to fit the document thickness so sheets sit firmly without folding. To label the contents, place a title sheet or adhesive label inside the clear front or write on the opaque back if suitable. For transport, ensure the edge opposite the open side is aligned to prevent pages from sliding out.

Usage recommendations

Store covers flat in a dry environment to maintain shape and avoid warping. For long-term archiving combine with acid-free interleaving if required; avoid prolonged exposure to direct sunlight to prevent discoloration of the opaque back panel.
