Replacement Refill for Demon Slayer Ballpoint Pen, Black Ink

Product Description and Use

The replacement refill is of a standard type suitable for ballpoint pens. The refill body is made of transparent/black plastic, allowing you to easily check the ink level. The ink colour is classic black, ideal for general writing, school, work, and signing important documents.

How to Correctly Use the Refill (Replacement)

  1. Unscrew the Ballpoint Pen: Carefully unscrew the body of your Demon Slayer ballpoint pen in the middle, or where the top and bottom parts join.
  2. Remove the Old Refill: Take out the empty cartridge. It may be necessary to first unscrew it from the tip mechanism if it is held in this manner.
  3. Insert the New Refill: Insert the new black replacement refill, ensuring it is firmly seated in the tip mechanism.
  4. Reassemble the Pen: Screw the pen back together, and you can continue writing!

Please Note: This refill is specifically designed for Demon Slayer ballpoint pens No. 84320, 84321, and 84322. For the best result, only use it for these models.

Care and Storage

For the longest possible lifespan and smooth writing, we recommend storing the replacement refill at room temperature. Avoid direct sunlight and extreme temperatures (both high and low), which could damage the ink or cause it to dry out. If you are not currently using the refill, store it in its original packaging or in a stationery case.
