• World-Renowned Vellum Paper: Crafted from Clairefontaine’s signature 90g satin-finish vellum, these envelopes are remarkably bright, opaque, and incredibly smooth to the touch.

• Superior Opacity: The high-density paper ensures that your private correspondence remains private. Even under bright light, the contents of your letter will not show through.

Clairefontaine envelopes are the preferred choice for the dedicated correspondent for three key reasons:

1. The Professional Touch: The brilliant white finish and crisp edges convey a level of professionalism and respect that standard office envelopes cannot match.

2. Ink Versatility: The smooth surface is a playground for calligraphers and pen enthusiasts, allowing nibs to glide effortlessly while showcasing the true color of your ink.

3. Time-Saving Luxury: The self-sealing mechanism is a modern convenience that doesn't compromise the "old-world" feel of the high-quality French paper.
