Converter-Type Brush Pen This brush pen uses a converter (suction device) to draw ink from an ink bottle, allowing it to be used like a watercolor marker. To use, twist the top of the converter to absorb ink and then attach it to the pen body. The brush pen tip is a bristle type, allowing for a realistic brush pen feel. The writing feel is smooth, allowing for fluid writing. It is recommended not only for writing characters but also for creating watercolor paintings, illustrated letters, and illustrations. ◆ What is a converter? It is an ink suction device used to draw ink from an ink bottle into a fountain pen. Attach the converter, immerse the pen nib up to the neck in ink, and use the rotary suction method to absorb the ink. ● Please use dye-based ink for fountain pens (sold separately). ---------------------
