Features: 
This pen is stronger and more durable than ordinary fountain pens, but if it is improperly used and kept, it is often impossible to write characters. This is mainly because the dry ink sticks around the steel ball and prevents the ink from flowing out. When using a ballpoint pen, do not write on oily or waxy paper, otherwise the oil or wax will be embedded in the copper bowl along the edge of the steel ball, which will affect the output of the oil and make it impossible to write. Also, avoid pen impact, exposure, and when not in use. Wear a pen cap with gloves to prevent damage to the pen tip, deformation of the pen barrel, and oil leakage from the pen core to contaminate the body. In case of cold weather or left unused for a long time. When the pen does not produce oil, you can soak the pen tip in warm water for a while and then draw the pen tip on the paper to write.
 
Bumps caused by the tip of a ballpoint pen falling on the ground. If the tip of the pen touches the ground at 90 degrees, the tip of the ballpoint pen will not be damaged. The ball will fall off and writing is difficult.
The correct writing angle of the ballpoint pen (55°~70°) When writing with a ballpoint pen, it is most ideal to control the angle at 55° to 70°. At this time, only the ball is in contact with the paper, and the closing part does not touch the writing, so as to ensure the ballpoint pen Extend the service life under good writing conditions.
If the writing angle is too small, it is easy to wear the ball seat (the ball seat material is nickel-platinum copper or stainless steel, which is much easier to wear than the ball). If the writing object is contacted for a long time, even if the writing object is paper, the ball seat will also be worn. No wear, it will cause the ball to fall off.
When writing, the pad of paper is too thick, the tip of the pen touches the paper, and it is easy to wear and fall off. Suggestions: 0.4 balls can not be copied; 0.5 balls can be copied at most 1, not more; 0.7 balls can be copied at most 3 Up to 4 sheets, no more. It is best to write at 75° when copying.
