Gold Pen (Fluid Writer Pen) Instant purchase OK. By pouring liquid paints such as glaze or gold paint into the head (inkwell) shown in image 7, the paint will gradually come out from the pen tip below. It is convenient for drawing delicate lines in overglaze decoration. It is suitable for line drawing and fine patterns using overglaze paint dissolved in gold liquid or pen work oil. You can draw fine lines of approximately 0.5mm. (After use, to prevent the ink from hardening, insert the included needle into the pen tip as shown in image 8.) There are no noticeable scratches or stains, but please understand that it is not new. Thank you for viewing.
