Today topic and short description on pen.The wellspring pen is a round and hollow handheld composition apparatus utilized for making lines and stamps on paper and level permeable surfaces. The pen comprises of two principle parts: a removable cozy fitting top and the utilitarian barrel-body containing a fluid ink save, anchored by a feeder and sharp metal nib. The device works by gravity and capillarity, discharging ink through the feeder when light weight is connected to the nib tip against paper. Gravity pulls ink from the interior holding chamber, while the outside feeder and a little air gap in the nib serve to help in ink stream control.
Ink supply is renewed by expelling the store, crushing while at the same time holding it vertically in a jug of ink and discharging to enable hairlike activity to draw ink into the repository. On the other hand, a dispensable ink cartridge might be embedded onto the feeder.
