The core of a pen, an accessory to a writing tool, can be replaced many times.

A tube with ink or ink in the ballpoint pen tube, with a metal pen tip at the front and a writing ball embedded in the pen tip, also refers to the graphite strip (pencil lead) in the pencil. The pen lead is a rubber tube or a suction pipe in the pen tube. Common neutral core pen head diameters of 0.5 mm, 0.7 mm, 0.38 mm, 0.35 mm, 0.3 mm, 0.25 mm should be used properly, otherwise it will cause uneven oil production.

The neutral core can be assembled with a miniature pen maker.
