How to use

To replace the refill, unscrew the barrel of your compatible pen by twisting the grip section or the end cap. Carefully remove the empty refill tube and insert the new UMR-85 refill, ensuring it is seated correctly in the housing. Once the refill is in place, screw the pen barrel back together securely. Before writing, you may need to scribble on a scrap piece of paper for a few seconds to initiate the ink flow.

What to consider before purchase

• Verify that your current pen model is compatible with the UMR-85 refill size
• Check the tip size requirements for your specific writing needs
• Ensure the pen barrel is in good condition before replacing the internal component

Usage recommendations

For optimal performance, store your pens with the tip facing downward or horizontally when not in use to maintain consistent ink flow. Avoid exposing the pen to extreme temperatures, as this can affect the viscosity of the gel ink.
