Herlitz C4 Envelopes with Window, 229 x 324 mm, 90 g/m², Peel & Seal Closure, White, Pack of 10 Mailing Bags

The Herlitz 10900702 is a pack of 10 white C4 mailing bags (229 x 324 mm) with an address window, made of 90 g/m² paper with a peel-and-seal closure, for sending A4 letters, contracts, certificates and brochures flat — without folding.

C4 is the envelope size for unfolded A4. The address window lets you print the recipient address on the document itself, which saves addressing each envelope by hand, and the peel-and-seal strip closes cleanly without moistening.

• 10 x Herlitz C4 mailing bags with window, white, 90 g/m², peel & seal (article 10900702)
• Shrink-wrapped pack

• A4 documents go in flat: no creases on contracts, certificates, drawings or brochures.
• The window shows the address printed on your letter — position the address block of your template accordingly.
• Peel & seal: remove the protective strip and press — no water, no glue stick, and a clean closure.
• 90 g/m² paper is sturdier than standard copy paper, so the bag holds a few sheets without tearing.

• It does not fit folded A4 in a DL or C5 layout — C4 is for unfolded A4 only.
• Herlitz does not publish the window size or position; check that your letter template's address block lines up before printing in volume.
• It is not a padded or bubble envelope — it gives no shock protection for objects.
• It is not suitable for thick catalogues or binders that need a gusseted envelope.
