Nel 1948 la ''Stiassi e Tantini'' si sciolse definitivamente, ma la famiglia Tantini proseguì per un certo periodo le attività con la ''P. Tantini & C Srl''; venne aperta a Bologna una attività commerciale sotto questo nome, ma la produzione delle stilografiche non si estende oltre gli anni '50. Con la crisi derivante dal successo della penna a sfera usa e getta le attività dell'azienda si diversificarono nel commercio di inchiostri, materiale da cancelleria e chincaglierie, fino al fallimento avvenuto nel 1972.

In 1948 ''Stiassi e Tantini'' was closed, but the Tantini family continued its activities for some time with ''P. Tantini & C Srl'' company. In Bologna a business under this name  was opened, but the fountain pen production does not extend beyond the 50s. With the crisis resulting from the success of the disposable ballpoint pens the assets of the company was diversified in the business of ink, office supplies, and knickknacks, until the final failure occurred in 1972.
