Writing media that are water-based are known as water-based ballpoint pens (water-based ink pens), also referred to as ballpoint pens or rollerball pens. They combine the characteristics of fountain pens and oil-based ballpoint pens, offering smooth and even writing. The pen bodies and caps are made in three ways: plastic injection molding, stainless steel stamping and grinding, or stainless steel manufacturing. The tip of the pen comes in two types: cannonball and syringe, made from copper alloys, stainless steel, or engineering plastics. The ball beads are typically made from stainless steel, hard alloy, or aluminum oxide, with medium-sized ball beads measuring 0.7mm in diameter and fine-pointed ball beads measuring 0.5mm. The ink storage can be fiber bundle or non-fiber bundle, and the most common ink colors include red, blue, black, and green. We know that fountain pens are also called fountain pens because the ink they use is made from tap water and water-soluble ink powder, so fountain pens are water-based pens. The liquid in the ballpoint pen is oil-based, so ballpoint pens are oil-based pens. The liquid in the neutral pen is neither the same as the ink in the fountain pen nor the oil-based liquid in the ballpoint pen, but rather an organic solvent.Therefore, it is called a neutral pen. A neutral pen contains an organic solvent, which is thicker than oil-based ink but thinner than water-based ink. When writing, the ink turns from a semi-solid state into liquid ink at the tip of the pen. The biggest advantage of neutral ink is that each drop of ink is used at the tip of the pen, without evaporation or leakage, thus providing a smooth and smooth writing feeling, with smooth and stable ink flow.
