The specific operation steps are as follows:

1. Pick up the seal in one hand, squeeze the seal into the middle, pinch the ink cartridge in the middle of the seal with two fingers, and gently try to push it out. Then the ink cartridge comes out, slowly take out the ink cartridge and put it on the desktop.

2. Remember when we took the ink box, took off the lid and slowly added ink to the ink box. Be careful not to add too much, the ink cartridge is very small, and it is easy to overflow if you add too much. Will stain our hands and desktops with ink.

3. Drop a few drops at each position of the ink cartridge until the ink cartridge is completely covered. After adding ink, don't worry about putting the ink cartridge back on the seal. Continue to put the ink cartridge on the table for five minutes, so that the ink can completely soak the ink cartridge, which is beneficial to our long-term use, instead of adding it every two or three days.

When the ink in the ink box is almost submerged, we will slowly pick up the ink box. Press the seal to the middle with one hand, and push the ink cartridge to the middle with the other hand. In the whole process, pay attention to spill the ink and press the seal properly to prevent the space in the middle of the seal from being insufficient and the ink cartridge from entering.

After the seal is installed, we find a piece of white paper and cover it several times. It was unclear at first, but it was all ink, and then it gradually became clear. In this way, we successfully inked the seal.
