The Treccani weekly diary, in black eco-leather, foil-printed in the same colour, offers a sober and elegant style and is entirely made in Italy. Combining functionality and design, caring craftsmanship and conceptual flair, knowledge and know-how, the Treccani diary brings with it an invitation to rediscover the history of the agenda diary and the etymology of the word "agenda", through its definition in the Treccani Vocabolario.
