Unscrewing the bottom, it is possible to extract the cylindrical piston, which slides tightly with respect to the body of the pen, and to carry out the pumping action through it. The mechanism is very functional and clearly more advanced than the [[vacumatic filler|vacumatic]] and other similar systems because unlike that it does not require membranes or other flexible rubber elements, and has a greater mechanical simplicity. The disadvantage is the slightly larger size of the mechanism.
