This group brings together all those systems that require that the filling takes place through the creation of a depression inside the body of the pen so that the ink is sucked through it. In this case it is generally the body of the pen itself that acts as a reservoir, and can be made of transparent material so as to allow the visualization of the ink level.

Come per gli altri sistemi che usano il corpo della penna come serbatoio anche in questo caso si ha il vantaggio di poter disporre di un maggior volume per contenere l'inchiostro, ma si ripresenta lo svantaggio che l'aria residua contenuta nel serbatoio è sensibile alle variazioni di temperatura, il che rende più facile, per l'aumento di volume in caso di riscaldamento, i casi di perdite di inchiostro, specie quando la penna è quasi scarica ed il volume di aria maggiore.

As with other systems that use the pen body as a reservoir, this also has the advantage of having a greater volume to contain the ink, but the disadvantage is that the residual air contained in the reservoir is sensitive to changes in temperature, which makes it easier, due to the increase in volume in case of heating, the cases of leakage of ink, especially when the pen is almost discharged and the volume of air is greater.
