lamy ballpoint pen is a water-based ballpoint pen. The writing principle of the ball pen is mainly to use the direct contact between the ball and the paper surface to generate friction when writing, so that the ball can roll in the ball seat and bring out the ink or ink in the refill to achieve the purpose of writing.

the ballpoint pen adopts the manufacturing method of "integrated molding", the pen body and the pen cap are designed as closed seamless components, and the surface decoration is creatively finished by computer numerical control technology and robot-assisted grinding, so it can polish a unique horizontal texture in a round and small pen body.

Extended information:

Ballpoint pens are more durable than ordinary pens, but if they are not properly used and kept, they often can't write words, which is mainly because the dry ink sticks around the steel balls to prevent the ink from flowing out. Ink is a kind of viscous oil, which is made of linseed oil, synthetic pine nut oil, mineral oil, hard rubber and lampblack.

When using a ballpoint pen, don't write on paper with oil and wax, or the oil and wax will be embedded in the copper bowl along the edge of the steel ball, which will affect the oil production and make it impossible to write. Also, avoid the impact and exposure of the pen, and wear the cap with gloves when not in use, so as to prevent the pen tip, the pen holder from being damaged, and the refill from leaking oil and polluting objects.

if it is cold or left unused for a long time. When the pen is out of oil, you can put the pen tip in warm water for a while and then stroke the pen tip on the paper to write words.
