You can try: Step 1: Open the bottom cover of the seal; Step 2: add ink to the surface of the seal; Step 3: Turn the seal over and wait for the ink to penetrate; Step 4: After the ink has completely penetrated, it can be directly stamped.
When adding ink, literally drop a small amount of ink. It is not advisable to add too much ink at a time. It is best to use the original ink of the same brand, otherwise it may not be added because of improper use of ink.
thank you
