From the Jacques Herbin site:
"To celebrate the 350th anniversary of Jacques Herbin’s original brand, we are letting the people who know us best, our fans, choose the new colour of our next anniversary ink. This will form part of the official Jacques Herbin collection.
Our ink experts have designed four very distinct shades. The range varies from pastel to dark, soft to flamboyant and tender to lively, each with shimmering and radiant reflections. Each one unique. And to mark this vintage in an even more spectacular way, we decided to create a unique Jacques Herbin ink with both silver and gold glitter that will add sparkle to your writing!
So what do you need to do? You have until 16th March to vote and let us know your favourite below. The result will then be verified, and we will reveal the results by email in early April. As if you needed more of a reason to vote, the Jacques Herbin team will then randomly select FIVE voters to exclusively preview the new ink in the luxury of their own home.
The winning ink will be available from selected stationery retailers, ink specialists and boutiques for purchase from September 2020."
