Step 2: Locate the Release Mechanism of the Pen Most pens have a small mechanism or button that needs to be pressed or slid to release the refill. Find this mechanism, usually located at the end of the pen. Step 3: Remove the Old Refill Gently hold the end of the pen and pull out the old refill. Some pens may require more force or a rotational motion to remove the refill. Step 4: Install the New Refill Insert the new refill into the pen, ensuring it aligns with the release mechanism. Then gently press or slide the mechanism to secure the new refill. Step 5: Test the New Refill After replacing the refill, write a few words to test if the new refill is installed correctly and can be used normally. **Precautions**: Caution 1: Avoid Excessive Force When pulling out and installing refills, avoid using too much force to prevent damaging the internal structure of the pen or the new refill. Caution 2: Keep Hands Clean Keep your hands clean during the process to avoid ink or dye staining your hands or other items. Caution 3: Choose a Suitable Refill Ensure the chosen refill is compatible with your pen to avoid installation problems or damage caused by mismatch. Caution 4: Properly Store Spare Refills After replacing the refill, properly store or dispose of the old refill for future use or disposal.
