Goulet Pens, Cult Pens and the French listing we read don't state where the Triomphe envelopes are made, and Clairefontaine's French site doesn't list them. Clairefontaine makes its Pollen envelopes in France, but we found no statement for Triomphe envelopes. ## Key takeaways - A pack holds 25 C6 envelopes, 114 × 162 mm (4.5 × 6.4 in), item 7736C. - Goulet Pens lists 100 g paper; a French price listing gives 90 g/m², so the weight depends on the source. - Goulet says each envelope has a white tissue lining over an opaque grey layer, so the letter can't be read through it. - Goulet Pens ranked it No. 33 on its best-seller list on October 22, 2026; a pack sits in our $$ band, $5–20. - An A5 sheet (148 × 210 mm) folded once to 148 × 105 mm leaves about 7 mm to spare on each side. ## What are Clairefontaine Triomphe small envelopes? **They're the C6 envelopes made to match Clairefontaine's Triomphe letter paper: bright white, self-sealing and lined so the letter inside stays private.** Goulet Pens sells them in packs of 25 and describes them as fountain pen friendly. On October 22, 2026, they were No. 33 on Goulet Pens' best-seller list, the highest-ranked paper product on it. They pair with the [Clairefontaine Triomphe pad](https://stationerytimes.com/guides/clairefontaine-triomphe-pad/), sold separately. ## Triomphe small envelope specs | Spec | Triomphe small envelopes | |---|---| | Item | 7736C (barcode 3329680773606) | | Size | C6, 114 × 162 mm (4.5 × 6.4 in) | | Count | 25 per pack | | Paper | Bright white vellum; 100 g (Goulet) or 90 g/m² (French listing) | | Lining | White tissue over an opaque grey layer (Goulet) | | Seal | Self-adhesive, peel-off strip | | Fits | A5 sheet folded in half; A6 card | | Price band | $$ ($5–20 per pack) | The two paper weights come from different sellers, and Clairefontaine doesn't publish a spec page for the envelopes, so we give both. In France, the listing we read showed €3.89 (about US$4.40) a pack on October 22, 2026. ![C6 Triomphe envelope 162 × 114 mm drawn to scale with an A5 sheet folded to 148 × 105 mm inside, about 7 and 4.5 mm to spare](https://stationerytimes.com/images/clairefontaine-triomphe-small-envelopes-fit.svg) *An A5 letter folded once fits with a little room on each side.* ## What fits inside? **An A5 sheet folded once, or an A6 card.** A5 is 148 × 210 mm; folded in half it's 148 × 105 mm, which leaves about 7 mm on each side and 4.5 mm top and bottom in a 162 × 114 mm envelope. A US letter sheet would have to be folded into quarters. For A4 or letter paper folded in thirds, Goulet sells the larger Triomphe envelopes (7735C), 4 3/8 × 8 5/8 in. Our [paper sizes explained](https://stationerytimes.com/guides/paper-sizes-explained/) guide lists the A and C sizes. ## Which Triomphe paper goes with them? **The A5 Triomphe tablet, blank or lined.** Goulet lists it as 50 sheets of 90 g/m² acid-free, pH-neutral paper, 148 × 210 mm, and says the small envelopes are made to match it. The blank A5 pad comes with a lined guide sheet to slip under the page, and the lined version has 8 mm ruling. Either sheet folded once fits a small envelope; for the A4 tablet, folded in thirds, use the large envelopes. Buying both from the same range gives a matching bright white set for letters. A pack of 25 envelopes covers half a 50-sheet pad if each letter uses one sheet, or the whole pad at two sheets per letter. ## Who are they for? **Letter writers and pen pals who want plain, opaque white envelopes in the European C6 size.** The lining matters if you write in dark fountain pen ink, which can show through thin envelopes. They're also a good size for thank-you notes and A6 greeting cards. For coloured C6 envelopes, Clairefontaine's Pollen range is the alternative below. ## Why are they lined? **For privacy.** Goulet says each envelope has a white tissue lining with an opaque grey layer, so writing inside can't be read through it. Cult Pens describes the same: the inside of each envelope is lined with an extra layer of paper for security. ## How do they compare with Pollen C6 envelopes? **Same C6 size, different purpose: Triomphe is white and lined, Pollen is coloured.** | | Triomphe small | [Pollen C6](https://stationerytimes.com/guides/clairefontaine-pollen-c6-envelopes/) | |---|---|---| | Size | 114 × 162 mm | 114 × 162 mm | | Colour | Bright white | 23 colours and finishes | | Paper | 90 or 100 g | 120 g/m² | | Lining | Yes, white and grey | No | | Pack | 25 | 20 | Pollen figures are from our Pollen guide, sourced from Clairefontaine. For a decorative seal over the flap, see [Rifle Paper Co.'s Gemma envelope seals](https://stationerytimes.com/guides/rifle-paper-co-gemma-envelope-seals/). ## Where are Triomphe envelopes made? **Clairefontaine doesn't say.** Clairefontaine's French site lists the Triomphe notebooks but not the envelopes, and Goulet, Cult Pens and the French listing we read don't state a country. Clairefontaine is a French paper maker; in the US, its products are sold through the distributor Exaclair. ## Frequently asked questions ### What size are Clairefontaine Triomphe small envelopes in inches? Goulet Pens lists them at 4 1/2 by 6 3/8 inches, the C6 size of 114 × 162 mm. ### Do Triomphe envelopes fit a US letter sheet? Not well. They're made for an A5 sheet folded in half; a US letter sheet would need folding into quarters. For A4 or letter paper folded in thirds, use the larger Triomphe envelopes. ### Are Triomphe envelopes self-sealing? Yes. Goulet calls them self-sealing, and the French listing describes an adhesive strip you peel off. ### Can you write on Triomphe envelopes with a fountain pen? Goulet describes them as fountain pen friendly, like the Triomphe paper they match. We haven't tested them yet. ### How many envelopes come in a pack? Twenty-five, per Goulet Pens and Cult Pens. ### Are Triomphe envelopes made in France? Clairefontaine is a French brand, but neither Clairefontaine nor the retailers we read state where these envelopes are made. ## Sources - [The Goulet Pen Company: Clairefontaine Triomphe Small Envelopes (CF-7736C, UPC 3329680773606; 25 self-sealing envelopes, 4 1/2 × 6 3/8 in, 100 g, white tissue and opaque grey lining; read October 22, 2026)](https://www.gouletpens.com/products/clairefontaine-triomphe-small-envelopes) - [The Goulet Pen Company: Best sellers (Triomphe Small Envelopes at No. 33, October 22, 2026)](https://www.gouletpens.com/collections/best-sellers) - [The Goulet Pen Company: Clairefontaine Triomphe Large Envelopes (CF-7735C, 4 3/8 × 8 5/8 in, for A4 folded in thirds)](https://gouletpens.com/products/clairefontaine-triomphe-large-envelopes) - [Cult Pens: Clairefontaine Triomphe 114 × 162 C6 size envelopes (pack of 25, lined, for A5 folded in half)](https://cultpens.com/products/clairefontaine-triomphe-114-x-162-c6-size-envelopes) - [Touslesprix (France): Clairefontaine 7736C, étui de 25 enveloppes Triomphe vélin blanc, doublure blanche, adhésive avec bande, 90 g/m², C6 (€3.89)](https://www.touslesprix.com/achat,enveloppes-90-x-114.html) - [Clairefontaine (French site): Triomphe range (carnet piqué and cahier; envelopes not listed)](https://www.clairefontaine.com/fr/4248-21390-carnet-pique-triomphe-36120c.html)
