<p>The present innovation concerns a writing instrument formed by a main body (1) containing a conventional ballpoint pen mechanism (4), provided in the upperpart with a reservoir (7) to store anticounterfeiting liquid which is closed by a cap (2) in which is attached a little brush (10). By means of a push pressure on the cap the point (5) of the pen advances and/or retracts, while the unscrewing of the cap permits the extraction of the little brush from the reservoir of anticounterfeiting liquid at the moment of use to apply and spread the forementioned liquid onto the important parts of the negotiable document (checks, bills and similar) amount payable in numbers and in letters, the addressee and the signature.</p> |
