Overview of water-based ballpoint pens

Water-based ballpoint pens are also known as ballpoint pens or ballpoint pens. Ball-point pens whose barrels and covers are made of plastic injection molding are called all-plastic ball-point pens; those whose barrels and covers are made of stainless steel are called semi-steel ball-point pens; those whose barrels and covers are made of stainless steel are called all-steel ball-point pens. The full plastic type is basically one-time use, that is, it is scrapped when the ink is used up; the semi-steel type and the full-steel type mostly use a replaceable refill type structure. The nib of the ball-point pen is divided into two types: cannonball type and needle tube type, which are respectively made of copper alloy, stainless steel or engineering plastic. The balls are mostly made of stainless steel, cemented carbide or alumina. The diameter of the ball with medium handwriting is 0.7 mm, and the diameter of ball with fine handwriting is 0.5 mm. There are two types of water storage: fiber bundle water storage and no fiber bundle water storage. The colors of ink are red, blue, black, green and so on. The ball-point pen has the characteristics of both a fountain pen and an oil-based ball-point pen, with smooth and smooth writing and even lines. It is an ideal writing tool.
