Preparation: Prepare the necessary tools and materials, which include a pen with a refill that needs to be replaced, a new refill, and a clean piece of paper or cloth (to keep the workspace clean). 2. Identification of Replacement Location: Different pen models have different ways to replace the refill. Observe the pen body and find the fixed part or disassembly port of the refill. 3. Removal of Old Refill: Hold the pen body and gently rotate or push the old refill to loosen it and take it out of the pen body. Avoid using too much force to prevent damaging other parts. 4. Cleaning the Interface: Use a piece of paper or cloth to gently wipe the inside of the pen body and the refill interface to ensure there is no ink residue or other debris. 5. Installation of New Refill: Insert the new refill into the pen body, paying attention to the front and back directions. Most pens have anti-stupid design to prevent incorrect installation. Gently rotate or push the new refill until it is securely seated. 6. Testing: After replacement, try writing to confirm that the new refill is working properly. **Precautions**:
