Ball beads are mostly made of stainless steel, hard alloy or alumina. The diameter of the ball in the middle of the handwriting is 0.7 mm, and the diameter of the ball in the fine handwriting is 0.5 mm. The water storage form is divided into two types: fiber bundle storage and fiberless bundle storage. The color of ink is red, blue, black, green and so on.

Common ball diameters are 1 mm, 0.7 mm, and 0.5 mm in diameter (the pen body or ballpoint pen tends to indicate this). Ballpoint pen inks are specially made, mainly made of pigments, solvents and tackifiers. Common colors are blue, black, and red.
