1. This pen is stronger and more durable than ordinary fountain pens, but if it is improperly used and stored, it is often impossible to write words. This is mainly because the dry ink sticks around the steel ball and prevents the ink from flowing out. The ink is a kind of viscous oil, which is prepared with flax seed oil, synthetic pine nut oil (mainly containing terpene alcohols), mineral oil (oil obtained by fractionating petroleum and other minerals), hard glue and oil fume, etc. .
2. When using a ballpoint pen, do not write on oily or waxed paper, otherwise the oil and wax will be embedded in the copper bowl along the edge of the steel ball to affect the ink and not write. Also, avoid pen impact and exposure. Always wear the gloves with the pen cap to prevent damage to the pen tip, deformation of the pen barrel, and oil leakage from the pen core. 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.
3. The ballpoint pen has a big shortcoming: the handwriting it writes is very clear at first; but it can’t stand the test of time. Over time, the handwriting will slowly become blurred. This is because the ink of the ballpoint pen is made with dyes and castor oil. Oil is not the same as water. It is not easy to dry. As time goes by, the oil will slowly soak on the paper and the writing will become blurred. Therefore, the ballpoint pen can only be used as an ordinary writing pen. If you want to keep your handwriting for a long time, you need to use a pen. [4]
4. When the ballpoint pen falls to the ground, if the tip of the pen touches the ground at 90 degrees, the tip of the ballpoint pen will not be damaged, but if the closing part is bumped, the phenomenon of “oiling” will occur at the gap. In severe cases, the ball will fall off and appear. Phenomena such as writing difficulties.
