The sale of Moleskine, the maker of sleek notebooks modelled on those used by novelists Bruce Chatwin and Ernest Hemingway, will earn a €323 million ($363 million) profit for the European private equity firm that bought the company a decade ago.

Syntegra Capital bought a majority stake in Milan-based Moleskine in 2006, investing €17 million. It will earn a total of 19 times as much when the sale of its remaining stake is completed, managing partner Marco Ariello said in an interview. D'Ieteren, a Belgian family-owned company, said on September 22 that it will buy Moleskine and delist its shares from the Milan stock exchange.
