Envelope C5 Clairefontaine Pollen by Clairefontaine, gold, 120 g/m², pH-neutral, acid-free

Envelope C5 Clairefontaine Pollen by Clairefontaine, gold, 120 g/m², pH-neutral, acid-free is a C5-sized envelope made from 120 g/m² gold-coloured paper designed for correspondence, invitations and document presentation. The paper is pH-neutral and acid-free, which helps protect contents from long-term deterioration and makes the envelope suitable for archival-safe storage. The envelope measures approximately 162 x 229 mm and offers a balance of stiffness and flexibility appropriate for reliable mailing and professional presentation.

Advantages

The envelope combines a premium-feel paper weight with acid-free, pH-neutral composition to provide protection against chemical degradation and to preserve documents. Its gold colour provides an attractive visual appearance for formal correspondence and invitations while the 120 g/m² paper ensures durability during handling and postal transit. Designed by Clairefontaine, the product follows material quality standards commonly expected for stationery used in both everyday and special-purpose communication.

Suitable for

• Mailing and sending letters or printed materials that fit C5 size
• Invitations, greeting cards and announcements requiring a coloured, high-quality envelope
• Archival-safe storage of documents where acid-free materials are preferred
• Presentation of certificates, photos or single-sheet documents

When it may not be suitable

This envelope is not intended for very heavy or bulky contents; items that exceed standard C5 dimensions or cause excessive thickness may not fit or may compromise the seal. It is also not a replacement for padded or reinforced mailing solutions when additional impact protection is required.

Key specifications

How to use

Insert the letter, card or document folded or unfolded to fit C5 dimensions, taking care that contents do not exceed recommended thickness. Close the envelope according to its closure type (internal flap adhesive or manual sealing) and press firmly to ensure a secure seal.

What to consider before purchase

• Check quantities needed; single-piece packaging may be sold individually

Usage recommendations

Use these envelopes for formal invitations, single-sheet certificates and correspondence where archival-safe, acid-free materials are preferred. Store unused envelopes flat and protected from moisture and direct light to preserve colour and paper integrity.
