1. Prepare ink bag: buy Schneider's standard ink bag, and the color of the ink bag can be selected according to your own preferences. The ink bag has two connecting ends, the thicker connecting end is the filling end and the needle-shaped connecting end is the discharge end.
2. Prepare the pen body: remove the handle of the pen body from the pen holder and take out the original ink bag.
3. Install the ink bag: insert the filling end into the circular hole of the ink chamber in the pen body, and then screw the filling end by hand until the ink bag is completely inserted, and the needle at the discharge end of the ink bag penetrates out of the ink chamber to the position of the pen head.
4. Start filling ink: Dip the pen tip into the ink cup, gently press the filling end of the ink bag by hand until the ink bag expands and is full of ink, then release your fingers and wait for the ink to ooze from the pen tip. At this time, the ink bag and pen tip are completely full.
5. Complete the installation: Gently rub the nib with your hands to make the ink in the nib evenly distributed. Then put the handle back on the pen.
It should be noted that when installing the ink bag, try to avoid being too tight to avoid damaging the pen body. When filling ink, you should also be careful not to squeeze the ink bag hard to avoid soiling clothes or other items. At the same time, in the process of use, to avoid ink solidification and blockage caused by long-term non-use, the pen head and ink room can be cleaned regularly.
