But with these pens to cause a leak is often sufficient only the heat of the hand that holds the pen. This is transmitted to the air contained inside the barrel, causing an expansion that alters the balance of pressure between inside and outside. This makes it relatively easy to obtain a loss of ink. Although today it is back in fashion in some models, for its ''retro'' taste, it remains, however, provided that it can really be considered as such, a primitive filling ''system''.
