[Note on pen use]]

  use and maintenance:

(1) protect the metal surface by plating (coating) layer, prevent hard metals from colliding and grinding, and avoid contact with acidic and alkaline solutions. It can be tested with soft cloth to keep the pen body fresh.

(2) There are two types of water storage structures: water-absorbing machine (single-purpose structure), water-absorbing machine and ink bag (dual-purpose structure).

(3) when using water-absorbing machine, please use high-quality ink without precipitation. Before stopping storage, wash the inside with clean water and dry it before storage. Before calling the ink, if it is not cleaned for a long time and then used, wash it first and then call the ink.

(4) do not use black ink containing gum to prevent silting from blocking the writing structure and affecting the water.

(5) plastic parts should not touch organic solvents such as sprinklers, and should not be placed at high temperature (65°C).

(6) the writing structure should not be disassembled by itself to avoid loss or damage of parts.

(7) ink bag and water-absorbing machine use:

a. Replace ink bag: remove the old ink bag and push the new bag into the front end of the pen with force. Put the spare ink bag into the pen holder as shown in the figure;
b. Insert rotary water-absorbing machine: push it into the front end of the pen with force, then rotate the tail water-absorbing machine, first rotate counterclockwise to air discharge, then rotate clockwise, that is, absorb ink;
c. Insert pull-out type water-absorbing machine: push it into the front end of the pen with force, and then push the pull rod, that is, suction ink.
D. Insert Pul-out piece spring type water-absorbing machine: push it into the front end of the pen with force, and then press leaf spring, that is, suction ink.
 (8) fountain pen cleaning:
if the water storage structure is a dual-purpose structure, take out the ink bag or water-absorbing machine, and immerse the tip of the pen and the front end of the pen into warm water Zhongzhi the accumulation of stains to soften;
after inserting water-absorbing machine, immerse the nib into warm water, then hold the tail of rotary water-absorbing machine and rotate it counterclockwise or clockwise (pull-out water-absorbing machine is to push the pull rod back and forth, and pul-out piece spring is to press the spring continuously), change the water for many times, it is appropriate until the water is clear, and finally dry it with a soft cloth for use;
for single-structure, simply immerse the nib into warm water, press water-absorbing machine continuously until the water is clear, and it will be used after drying
