GBC A3 Binding Covers Leathergrain 300gsm 25 Pack - Black BCL300A3BK25

GBC A3 Binding Covers Leathergrain 25 Pack - Black

GBC leathergrain binding covers in A3 provide a professional, textured card finish for large-format bound documents. At 300gsm, the covers are substantial enough to protect contents and hold their shape without sagging, and the black leathergrain surface gives bound documents a polished, finished appearance suited to professional and corporate presentation. Each pack contains 25 covers.

A PROFESSIONAL FINISH FOR LARGE-FORMAT BOUND DOCUMENTS

A3 binding covers suit documents that exceed the standard A4 format — large technical reports, architectural and engineering drawings, oversized presentations and any project where A4 is insufficient for the content. Binding covers at A3 size are less commonly stocked than A4, making them a useful product for professionals and businesses that regularly work with larger document formats and need a reliable, finished binding solution at that size. At 25 covers per pack, there's enough for up to 12 complete documents using one cover front and back, or 25 documents if pairing a leathergrain back cover with a clear front.

LEATHERGRAIN TEXTURE: A PREMIUM LOOK FOR BOUND WORK

The leathergrain surface is an embossed card texture designed to resemble the grain of leather — a finish long associated with professional document presentation in legal, corporate, architectural and engineering environments. It's more visually substantial than a plain card or gloss cover, giving bound documents an appearance that suits client-facing reports, formal proposals, tenders and presentation copies of significant work. Black leathergrain presents as formal and authoritative, making it the natural default for documents where the quality of presentation matters alongside the quality of content.

300GSM WEIGHT FOR PROTECTION AND RIGIDITY

At 300gsm, these covers are heavy enough to provide genuine protection for the pages inside — the card holds its shape, resists bending under normal handling and gives bound documents a firm, stable feel. Lighter covers can bow or flex at larger formats, which becomes more pronounced at A3 where the span of the cover is considerably greater than A4. The 300gsm weight keeps the document flat and the cover rigid across the full A3 surface, maintaining a professional appearance from the moment the document is handed over to when it's pulled from a shelf weeks later.
