Water-based ink is similar to colored pen, and contains no oil essence. Oily ink is more irritating and volatile because it contains oil essence. If the paint falls off the toy, you can use a marker to make up the color.

gel pen

A ballpoint pen with a viscosity between water and oil is called a gel pen. Gel pen originated in Japan and is a novel writing tool that is popular all over the world. Gel pen has the advantages of fountain pen and ballpoint pen, with comfortable writing feel, low ink viscosity and easy-to-lubricate substances, so it is smoother than ordinary oily ballpoint pen and is an upgraded product of oily ballpoint pen.

Bullet type

If we look closely at the tips of these gel pens, we will find that they are just like bullets. In the manufacturing process, we cut an original rod into a complete nib by metal cutting. The bullet type is suitable for making thicker pens, which are mostly 0.5MM in the market, and the thickest one can reach 1.2.

ball pen

Ballpoint pen, or ballpoint pen, is a kind of writing tool that uses dry and thick ink, which is brought out by the freely rotating steel ball on the pen head and transferred to paper. It has the advantages of no leakage, no weather influence, long writing time, no need to pour ink frequently and low price. It is the most popular writing tool in the world in recent years.

Watercolor pen is a common painting tool for children. Generally,12,24,36 colors are sold in a box. The nib is generally round, and the two colors are not harmonious together. Generally suitable for drawing children's pictures, and can also be used as markers.

ball pen

Simply put, a ballpoint pen or ballpoint pen is a water-based signature pen.

The writing principle of ballpoint pen mainly uses the direct contact between the ball and paper to generate friction, which makes the ball roll in the ball seat and bring out the ink or ink in the refill to achieve the purpose of writing.

A ballpoint pen is a pen that writes with ink and different pigments. The pen tip is a small steel ball embedded in a small cylindrical copper bowl, and then connected to a plastic pipe filled with ink. The ink flows down from all sides with the rotation of the steel ball.

The pigment of ballpoint pen ink is dye. There are three main colors of ink: blue, red and black, among which blue ink is the most used. In the past, the pigment components in blue ink were basic blue and basic purple, and the solvents were oxidized castor oil and ricinoleic acid. Basic dyes have been eliminated because of their poor light resistance (light resistance is only 1 -2), heat resistance, acid and alkali resistance and poor durability. The "424" blue ballpoint pen and "322" black ballpoint pen sold in the market have good durability.

It is often reported that scented ballpoint pens are toxic, and volatile organic compounds contained in inferior scented stationery are toxic and harmful to human body. However, we have not heard of poisoning caused by normal use of oily ballpoint pens without adding volatile organic compounds.
