  1. The barrel is molded from plastic resin.
  2. The barrel is screen printed.

  4. Plastic plug is inserted at one end of the barrel.
  5. Ink is injected at the other end of the barrel using a hypodermic-like needle.
  6. The tip (writing nib) is inserted in this same end.
  7. Plastic cap is placed on the marker. The ink slowly transfers to the new writing tip.
